TECHNICAL FIELD

The present disclosure relates to the field of optical imaging, and in particular to a camera module, a circuit board assembly and manufacturing method thereof, and an electronic device with the camera module.

BACKGROUND

Currently, electronic devices are increasingly developed to be more intelligent, lighter and thinner, which imposes more strict requirements on the size and imaging quality of camera modules, which is one of the standard configurations of electronic products.

On one hand, in order to meet the development trend of making the electronic products more intelligent, it is necessary to configure more intelligent modules or mechanisms for the electronic products, such as sensors, and improve the imaging quality of the camera modules. It is appreciated that, due to the development trend of making the electronic products lighter and thinner, the premise of configuring more intelligent modules or mechanisms for the electronic products is to reduce the size of other modules or mechanisms. The camera module occupies more space inside the electronic device due to its large size. Therefore, it is necessary to consider how to reserve, by reducing the size of the camera module, more space for the electronic product to be configured with more intelligent modules or mechanisms.

On the other hand, in order to meet the development trend of making the electronic products more intelligent, it is necessary to configure the camera module with a photosensitive element of a larger photosensitive area and passive electronic components larger in volume and amount, which may increase the size of the camera module inevitably and thus is disadvantageous for making the electronic products lighter and thinner. Both a photosensitive chip and a passive electronic component of a current camera module are attached to the same side of a circuit board. Such arrangement of the photosensitive chip, the passive electronic component, and the circuit board makes the passive electronic component to be disposed only along an outer peripheral side of the photosensitive chip, and a safe distance must be reserved between adjacent passive electronic components so as to avoid adverse effects on the imaging quality of the camera module due to the mutual interference between the adjacent passive electronic components, which causes the length and width of the camera module not to be reduced effectively. Those skilled in the art would understand that due to the higher and higher imaging quality requirements for the camera module and the increasingly large number of the passive electronic components, these passive electronic components are disposed around the photosensitive chip on the same side of the photosensitive chip in a mutually spaced manner, which may further increase the length and width of the camera module. Therefore, with the development trend of the camera module, the electronic device cannot be developed to be more intelligent, lighter, and thinner. That is, the development trend of the current camera module results in the effect that for the development trend of making the electronic device more intelligent, the camera module is required to provide good imaging quality, which results in an increase in the size of the camera module and thus is disadvantageous for making the electronic device lighter and thinner, while for the development trend of making the electronic device lighter and thinner, the volume of the camera module is required to be reduced, which results in reduction in the imaging quality of the camera module and thus is disadvantageous for making the electronic device more intelligent. Therefore, how to reduce the volume of the camera module while ensuring the imaging quality of the camera module is an urgent technical problem to be resolved.

FIG. 10 is a schematic diagram showing an internal structure of the camera module 100 taken along an intermediate position, and FIGS. 11A and 11B respectively show the stereoscopic state of the camera module 100 from different angels of view. Specifically, the camera module 100 comprises at least one optical lens 10, at least one photosensitive chip 20, and a circuit board 30, wherein the photosensitive chip 20 is conductively connected to the circuit board 30, the optical lens 10 is held in the photosensitive path of the photosensitive chip 20.

The light reflected by the object enters the interior of the camera module 100 from the optical lens 10, and then is received by the photosensitive chip 20 and imaged after photoelectric conversion. Electrical signals related to the image of an object obtained by the photoelectric conversion of the photosensitive chip 20 can be transmitted by the circuit board 30, for example, the circuit board 30 can transmit the electrical signals related to the image of the object to the device body 200 that is connected to the circuit board 30. That is, the circuit board 30 can be conductively connected to the device body 200 to mount the camera module 100 to the device body 200 to form the electronic device.

Further, with reference to FIG. 10 , the circuit board 30 comprises a substrate 31 and at least one electronic component 32, wherein each of the electronic components 32 is conductively connected to the substrate 31, respectively.

Generally, the substrate 31 is plate-like, and the front face 311 and the back face 312 of the substrate 31 are parallel to each other, so that the distance between the front face 311 and the back face 312 of the substrate 31 can be used to define the thickness of the substrate 31.

Nonetheless, it can be understood by those skilled in the art that in other examples of the camera module 100 of the present disclosure, at least one of the front face 311 and the back face 312 of the substrate 31 may be provided with a convex structure or a groove, and the camera module 100 of the present disclosure is not limited in this respect.

It is worth mentioning that the type of the substrate 31 is also not limited in the camera module 100 of the present disclosure. For example, the substrate 31 can be selected but not limited to a hard plate, a soft plate, a soft and hard combined plate, and a ceramic plate, etc.

Further, at least one of the electronic components 32 is conductively connected to the substrate 31 on the back face 312 of the substrate 31. Preferably, in this specific example of the camera module 100 of the present disclosure, all of the electronic components 40 may be conductively connected to the substrate 31 on the back face 312 of the substrate 31. In this way, the front face 311 of the substrate 312 does not need to reserve a position for connecting the electronic component 32, thereby facilitating reducing the length and width of the camera module 100.

It is worth mentioning that the type of the electronic component 32 is not limited in the camera module 100 of the present disclosure. For example, the electronic component 32 can be implemented as, but not limited to, a processor, a relay, a memory, a driver, a resistor, a capacitor, etc.

In a specific example of the camera module 100 of the present disclosure, the electronic component 32 can be attached to the back face 312 of the substrate 31, so that the electronic component 32 is conductively connected to the substrate 31 on the back face 312 of the substrate 31.

In another specific example of the camera module 100 of the present disclosure, the electronic component 32 may also be half-embedded in the substrate 31 on the back face 312 of the substrate 31, so that the electronic component 32 is be conductively connected to the substrate 31, that is, a portion of the electronic component 32 is exposed on the back face 312 of the substrate 31. In this way, the height of the camera module 100 can be further reduced. Alternatively, the electronic component 32 may also be entirely embedded inside the substrate 31.

In addition, the circuit board 30 may further comprise a connection plate 33, wherein the connection plate 33 has a module connection side 331 and a device connection side 332, and the module connection side 331 of the connection plate 33 is connected to the substrate 31. For example, the module connection side 331 of the connection plate 33 may be connected to the front face 311 of the substrate 31, or the module connection side 331 of the connection plate 33 may be connected to the back face 312 of the substrate 31. The connection manner between the module connection side 331 of the connection plate 33 and the substrate 31 is not limited. For example, the module connection side 331 of the connection plate 33 and the substrate 31 may be connected by, but are not limited to, conductive glue.

Nonetheless, it can be understood by those skilled in the art that the module connection side 331 of the substrate 31 is connected to the side face of the substrate 31, or it is possible that the module connection side 331 of the substrate 31 and the substrate 31 are integrally formed. The device connection side 332 of the connection plate 33 can be connected to the device body 200, for example, the device connection side 332 of the connection plate 33 can be provided or formed with a connector for being connected to the device body 200.

Generally, the connection plate 33 can be deformed, so that the connection plate 33 can buffer, in a manner of deformation, the displacement of the camera module 100 caused by the vibration of the electronic device during usage, thereby ensuring the reliability of the electronic device when it is used.

The photosensitive chip 20 is attached to the front face 311 of the substrate 31, and the photosensitive chip 20 is conductively connected to the substrate 31.

Specifically, the substrate 31 has at least one attaching area 313 and at least one bonding area 314, wherein the attaching area 313 and the bonding area 314 are both formed on the front face 311 of the substrate 31. Generally, the attaching area 313 of the substrate 31 is located in center, and the bonding area 314 surrounds the attaching area 313. For example, in this specific example of the camera module 100 shown in FIG. 10 , the attaching area 313 of the substrate 31 is located at center of the front face 311 of the substrate 31, and the bonding area 314 of the substrate 31 is located outer portion of the front face 311 of the substrate 31, and the bonding area 314 surrounds the attaching area 313. The photosensitive chip 20 is attached to the attaching area 313 of the substrate 31.

It can be understood by those skilled in the art that, in contrast to the traditional arrangement of electronic components along the periphery of a photosensitive chip, in the camera module 100 of the present disclosure, the photosensitive chip 20 and at least one of the electronic components 32 may correspond to each other in the height direction, that is, the photosensitive chip 20 and at least a part of at least one of the electronic components 32 may overlap when viewed from a top view, in such a manner that the bonding area 314 of the substrate 31 does not need to be reserved as an attaching position for attaching the electronic component 32, so that the area of the bonding area 314 of the substrate 31 can be further reduced, that is, the attaching area 313 of the substrate 31 can occupy a larger proportion of the front face 311 of the substrate 31. In this way, the length and width of the camera module 100 can be further reduced. Nonetheless, it can be understood by those skilled in the art that in some other examples of the camera module 100 of the present disclosure, the photosensitive chip 20 and the electronic components 32 that are respectively located at two faces of the substrate 31 may not overlap each other when viewed form the top view of the camera module 100. In addition, in some other examples of the camera module 100 of the present disclosure, at least one of the electronic components 32 may be disposed on both the front face 311 and the back face 312 of the substrate 31.

In addition, the manner in which the photosensitive chip 20 and the substrate 31 are connected is not limited in the camera module 100 of the present disclosure. For example, the photosensitive chip 20 has at least one chip connector 21, and the substrate 31 has at least one substrate connector 315. In one example of the camera module 100 of the present disclosure, the chip connector 21 of the photosensitive chip 20 may be directly connected to the substrate connector 315 of the substrate 31, for example, when the photosensitive chip 20 is attached to the attaching area 313 of the substrate 31, the chip connector 21 of the photosensitive chip 20 and the substrate connector 315 of the substrate 31 are directly connected. In another example of the camera module 100 of the present disclosure, the chip connector 21 of the photosensitive chip 20 and the substrate connector 315 of the substrate 31 may be connected through a set of connection wires 1000.

Specifically, after the photosensitive chip 20 is attached to the attaching area 313 of the substrate 31, the connection wire 1000 may be formed between the chip connector 21 of the photosensitive chip 20 and the substrate connectors 315 of the substrate 31 through a wiring process so as to conductively connect the photosensitive chip 20 and the substrate 31 by the connection wire 1000.

It is worth mentioning that the wiring direction of the connection wire 1000 is not limited in the camera module 100 of the present disclosure. For example, the wiring direction of the connection wire 1000 may be from the photosensitive chip 20 to the substrate 31, and also may be from the substrate 31 to the photosensitive chip 20. Nonetheless, it can be understood by those skilled in the art that the connection wire 1000 can also have other forming methods. In addition, the material type of the connection wire 1000 is not limited in the camera module 100 of the present disclosure. For example, the connection wire 1000 may be a gold wire, a silver wire, an aluminum wire or a copper wire.

It is also worth mentioning that the shape and arrangement of the chip connector 21 of the photosensitive chip 20 and the shape and arrangement of the substrate connector 315 of the substrate 31 are not limited in the camera module 100 of the present disclosure. For example, the chip connector 21 of the photosensitive chip 20 may be in a disk shape, a spherical shape, or the like, and the chip connector 21 of the photosensitive chip 20 is generally disposed in a non-photosensitive area of the photosensitive chip 20. Correspondingly, the substrate connector 315 of the substrate 31 may be in a disk shape, a spherical shape, or the like, and the substrate connector 315 of the substrate 31 is generally disposed in the bonding area 314 of the substrate 31. Preferably, after the photosensitive chip 20 is attached to the attaching area 313 of the substrate 31, the chip connector 21 of the photosensitive chip 20 and the substrate connector 315 of the substrate 31 are corresponding to each other so as to form, by a wiring process, the connection wire 1000 for connecting the photosensitive chip 20 and the substrate 31 between the chip connector 21 of the photosensitive chip 20 and the substrate connector 315 of the substrate 31.

In an embodiment of the camera module 100 of the present disclosure, the substrate 31, the electronic component 32, the connection plate 33, the connection wire 1000 and the photosensitive chip 20 form a circuit board assembly 2000. That is, according to another aspect of the present disclosure, the present disclosure further provides the circuit board assembly 2000, wherein the circuit board assembly 2000 comprises the substrate 31, the electronic component 32, the connection plate 33, the connection wire 1000 and the photosensitive chip 20, wherein the photosensitive chip 20 is conductively connected to the substrate 31 via the connection wire 20, and the electronic component 32 and the connection plate 33 are conductively connected to the substrate 31, respectively.

With continued reference to FIG. 10 to FIG. 11B, the camera module 100 further comprises a molding unit 40, wherein the molding unit 40 is integrally bonded to the photosensitive chip 20 and the circuit board 30 to form the circuit board assembly 2000 of the present disclosure. That is, the circuit board assembly 2000 of the present disclosure further comprises the molding unit 40.

Specifically, the molding unit 40 comprises a back molding portion 41, wherein the back molding portion 41 is integrally bonded to the substrate 31 on the back face 312 of the substrate 31, wherein the back molding portion 41 can reinforce the strength of the substrate 31 and ensure the flatness of the substrate 31, so that the photosensitive chip 20 attached to the attaching area 313 of the substrate 31 is kept flat so as to improve the imaging quality of the camera module 100.

The back molding portion 41 has good inertness. When the camera module 100 is used, heat generated by the photosensitive chip 20 is transmitted to the back molding portion 41, and the back molding portion 41 does not deform, in such a manner, the flatness of the substrate 31 and the flatness of the photosensitive chip 20 attached to the attaching area 313 of the substrate 31 are not affected by the heat generated by the photosensitive chip 20, thereby facilitating to ensure the flatness of the photosensitive chip 20. In addition, the back molding portion 41 may be formed of a material having a good thermal diffusivity so that the back molding portion 41 has a good heat dissipation property. After the heat generated by the photosensitive chip 20 is conducted to the back face molding 41, the back molding portion 41 can radiate the heat generated by the photosensitive chip 20 to the external environment of the camera module 100 in time so as to ensure the reliability of the camera module 100 when it has been used for a long time.

Preferably, the back molding portion 41 may be integrally bonded to the substrate 31 on the back face 312 of the substrate 31 by a molding process.

In an example of the camera module 100 of the present disclosure, the height of the back molding portion 41 is higher than the height of the electronic component 32, or the height of the back molding portion 41 is consistent with the height of the electronic component 32, for example, the distance between surfaces of the free side face 4111 of the back molding portion 41 and the back face 312 of the substrate 31 is greater than or equal to the height between the surfaces of the free side face of the electronic component 32 and the back face 312 of the substrate 31. It is worth mentioning that the free side face 4111 of the back molding portion 41 defined by the present disclosure is opposite to the bonding side face 4112 of the back molding portion 41, wherein the bonding side face 4112 of the back molding portion 41 is integrally bonded to at least a part of an area of the back face 312 of the substrate 31, with reference to FIG. 10 .

With further reference to FIG. 10 , it is assumed that the height of the back molding portion 41 is a parameter H, that is, the distance parameter between the bonding side face 4112 and the free side face 4111 of the back molding portion 41 is set to be H, the height of the electronic component 32 protruding from the back face 312 of the substrate 31 is a parameter h, wherein the numerical value of the parameter H is greater than or equal to the numerical value of the parameter h, so that when the camera module 100 is mounted, it is possible to prevent other mounting components from contacting the electronic component 32, thereby ensuring the reliability of the camera module 100.

In another example of the camera module 100 of the present disclosure, the back molding portion 41 embeds at least a part of the surface of at least one of the electronic components 32. Preferably, the back molding portion 41 embeds the entire surface of at least one of the electronic components 32. More preferably, the back molding portion 41 embeds the entire surface of the electronic component 32.

It is worth mentioning that the back molding portion 41 can isolate the surface of the electronic component 32 from the external environment by embedding the electronic component 32, thereby guaranteeing the good electrical property of the electronic component 32 by avoiding oxidation of the surface of the electronic component 32.

In addition, the back molding portion 41 can isolate adjacent electronic components 32 by embedding the electronic components 32 so as to guaranteeing the imaging quality of the camera module 100 by avoiding mutual interference between the adjacent electronic components 32. Moreover, since the back molding portion 41 can isolate the adjacent electronic components 32, and there is no need to reserve a safe distance between the back molding portion 41 and the electronic component 32, more electronic components 32 with larger size can be connected on a limited area of the back face 312 of the substrate 31, for example, more electronic components 32 with larger size can be attached to a limited area of the back face 312 of the substrate 31. In this way, the performance of the camera module 100 can be further improved.

It can be understood by those skilled in the art that the photosensitive chip 20 attached to the attaching area 313 of the substrate 31 and the electronic component 32 attached to the back face 312 of the substrate 31 are respectively located on both sides of the substrate 31, so that contaminants falling off from the surface of the electronic component 32 or contaminants such as solder powder falling off from a connection position between the electronic component 32 and the substrate 31 will not contaminate the photosensitive area of the photosensitive chip 20, and in this manner, the good product yield of the camera module 100 can be ensured. And preferably, the electronic component 32 is embedded by the back molding portion 41 integrally bonded on the back face 312 of the substrate 31, and in this manner, the surface of the electronic component 32 can be prevented from producing contaminants and the connection position between the electronic component 32 and the substrate 31 can be prevented from producing contaminants.

In addition, after the back molding portion 41 embeds the electronic component 32 located on the back face 312 of the substrate 31, the electronic component 32 can also prevent the back molding portion 41 from falling off from the back face 312 of the substrate 31 so as to ensure the reliability of the camera module 100.

With reference to FIGS. 10 and 11B, the back molding portion 41 has at least one mounting space 410, wherein the module connection side 331 of the connection plate 33 can be accommodated in the mounting space 410 of the back molding portion 41 after being connected to the substrate 31 on the back face 312 of the substrate 31. In this way, it is possible to prevent the module connection side 331 of the connection plate 33 from protruding to ensure the reliability of the connection position between the module connection side 331 of the connection plate 33 and the back face 312 of the substrate 31. Nonetheless, it can be understood by those skilled in the art that in other examples of the camera module 100 of the present disclosure, the back molding portion 41 may also embed the connection position between the module connection side 331 of the connection plate 33 and the substrate 31 to prevent the module connection side 331 of the connection plate 33 from falling off from the back face 312 of the substrate 31 so as to ensure the reliability of the camera module 100.

In some other possible examples of the camera module 100, the electronic component 32 that is not embedded by the back molding portion 41 can also be accommodated in the mounting space 410 of the back molding portion 41. In this way, when the camera module 100 is moved or mounted, the electronic component 32 can be prevented from being contacted, thereby preventing the surface of the electronic component 32 or the conductive position between the electronic component 32 and the substrate 31 from being destroyed so as to further ensure the reliability of the camera module 100. Alternatively, a portion of the surface of the electronic components 32 is exposed on the mounting space 410 of the back molding portion 41.

In addition, when the camera module 100 is mounted to the electronic device, the protruding mounting components of the device body 200 can also be accommodated in the mounting space 410 of the back molding portion 41. In this way, the internal space of the device body 200 can be effectively utilized so as to facilitate the lighting and thinning and miniaturization of the electronic device.

With continued reference to FIG. 10 to FIG. 11B, the molding unit 40 further comprises a molding base 42, wherein the molding base 42 has at least one light window 420, and the molding base 42 is integrally bonded to at least a part of the bonding area 314 of the substrate 31 and at least a part of the non-photosensitive area of the photosensitive chip 20 such that the substrate 31, the photosensitive chip 20, and the molding base 42 are integrally bonded, and the photosensitive area of the photosensitive chip 20 corresponds to the light window 420 of the molding base 42, thus, the light window 420 of the molding base 42 can provide a light path for the optical lens 10 and the photosensitive chip 20. That is, the light reflected by the object can pass through the light window 420 to be received by the photosensitive chip 20 after entering the interior of the camera module 100 from the optical lens 10.

It can be understood by those skilled in the art that the molding base 42 forms a part of the circuit board assembly 2000.

In a specific example of the camera module 100 of the present disclosure, the back molding portion 41 and the molding base 42 are simultaneously and integrally bonded to the back face 312 and the front side 311 of the substrate 31, respectively. That is, in the same molding process, the back molding portion 41 is integrally bonded to the back face 312 of the substrate 31, and the molding base 42 is integrally bonded to the front face 311 of the substrate 31. Nonetheless, in other examples of the camera module 100, the circuit board assembly 2000 of the present disclosure may also be formed by different molding processes, respectively.

In the present disclosure, the molding base 42 of the molding unit 40 is integrally bonded to the front face 311 of the substrate 31 by a molding process, such that there is no need for a connection medium such as glue between the molding base 42 and the front face 311 of the substrate 31. In this way, not only the manufacturing process of the camera module 100 can be reduced, but also the height of the camera module 100 can be lowered. It is more important that during the process of manufacturing the camera module 100, there is no need to worry that the connection medium such as glue contaminates the photosensitive area of the photosensitive chip 20, thereby ensuring the good product yield of the camera module 100.

In the present disclosure, the molding base 42 of the molding unit 40 is integrally bonded to the non-photosensitive area of the photosensitive chip 20, so that there is no need to reserve a safe distance between the molding base 42 and the photosensitive chip 20. In this way, the length and width of the camera module 100 can be further reduced, so that the camera module 100 is particularly suitable for being applied to electronic devices that are intended to be lighter and thinner.

It can be understood that, in the present disclosure, the molding base 42 of the molding unit 40 embeds the connection wire 1000, thereby being able to isolate the surface of the connection wire 1000 from the external environment to avoid oxidation of the surface of the connection wire 1000 so as to ensure the good electrical property of the connection wire 1000.

With continued reference to FIG. 10 , the camera module 100 comprises at least one filtering element 50, wherein the filtering element 50 is held between the optical lens 10 and the photosensitive chip 20, so that the light entering the interior of the camera module 100 from the optical lens 10 is received by the photosensitive chip 20 after passing through the filtering element 50. In this way, the imaging quality of the camera module 100 can be ensured.

Specifically, the filtering element 50 can filter stray light in the light entering the interior of the camera module 100 from the optical lens 10. In this way, the imaging quality of the camera module 100 can be improved. It is worth mentioning that the type of the filtering element 50 is not limited in the camera module 100 of the present disclosure. For example, the filtering element 50 may be, but not limited to, an infrared cut-off filtering element, a visible spectrum filtering element, etc.

Preferably, the filtering element 50 may be attached to a top surface of the molding base 42 such that the filtering element 50 is held between the optical lens 10 and the photosensitive chip 20.

With reference to FIG. 10 to FIG. 11B, the camera module 100 comprises at least one driver 60, wherein the optical lens 10 is drivably disposed in the driver 60, and the driver 60 is attached to the top surface of the molding base 42, so that the optical lens 10 is held in the photosensitive path of the photosensitive chip 20 via the driver 60. The driver 60 can drive the optical lens 10 to move along the photosensitive path of the photosensitive chip 20 relative to the photosensitive chip 20, so that the camera module 100 achieves automatic zooming and automatic focusing by means of adjusting the relative position of the optical lens 10 and the photosensitive chip 20.

It is worth mentioning that the type of the driver 60 is not limited in the camera module 100 of the present disclosure, as long as the optical lens 10 can be driven to move along the photosensitive path of the photosensitive chip 20 relative to the photosensitive chip 20. For example, the driver 60 may be implemented as, but not limited to, a voice coil motor in a specific example of the present disclosure.

Further, the driver 60 has at least one driving pin 61, wherein the driving pin 61 is electrically connected to the substrate 31. Preferably, the molding base 42 has at least one pin groove 421, wherein the pin groove 421 of the molding base 42 extends from the top surface of the molding base 42 to the front face 311 of the substrate 31, such that after the driver 60 is attached to the top surface of the molding base 42, the driving pin 61 of the driver 60 can extends, inside the pin groove 421, from the top surface of the molding base 42 to the front face 311 of the substrate 31, and the driving pin 61 of the driver 60 can be electrically connected to the substrate 31.

Preferably, the pin groove 421 extends, along the outer surface of the molding base 42, from the surface of the molding base 42 to the front face 311 of the substrate 31, thereby facilitating the electrical connection between the driving pin 61 of the driver 60 and the substrate 31 after the driver 60 is attached to the top surface of the molding base 42. It can be understood that the driving pin 61 of the driver 60 accommodated in the pin groove 421 of the molding base 42 does not protrude from the outer surface of the molding base 42. Therefore, not only the aesthetics of the camera module 100 can be ensured, but also an undesirable phenomenon of contacting the driving pin 61 of the driver 60 when assembling the camera module 100 at the device body 200 can be prevented so as to ensure the reliability and good product yield of the camera module 100.

Further, the top surface of the molding base 42 has at least one inner surface 422 and at least one outer surface 423, wherein the driver 60 is attached to the outer surface 423 of the molding base 42 such that the optical lens 10 is held in a photosensitive path of the photosensitive chip 20, wherein the filtering element 50 is attached to the inner surface 422 of the molding base 42 such that the filtering element 50 is held between the optical lens 10 and the photosensitive chip 20.

In some examples of the camera module 100 of the present disclosure, the plane where the inner surface 422 of the molding base 42 is located has a same height as the plane where the outer surface 423 is located. In some other examples of the camera module 100 of the present disclosure, there is a height difference between the plane where the inner surface 422 of the molding base 42 is located and the plane where the outer surface 423 is located. For example, in this specific example of the camera module 100 shown in FIG. 10 , the plane where the inner surface 422 of the molding base 42 is located is lower than the plane where the outer surface 423 is located, so that the molding base 42 forms at least one attaching groove 424, and the attaching groove 424 of the molding base 42 is in communication with the light window 420, wherein the filtering element 50 attached to the inner surface 422 of the molding base 42 is accommodated in the attaching groove 424 to further reduce the height of the camera module 100.

With reference to FIG. 1 to FIG. 9 of the accompanying drawings of the present disclosure, the manufacturing process of the camera module 100 is illustrated in the following description.

At the stage shown in FIG. 1 , the electronic component 32 is conductively connected to the substrate 31 on the back face 312 of the substrate 31, wherein two or more of the substrates 31 are disposed to form a jointed board unit 3000. It is worth mentioning that the arrangement of the plurality of the substrates 31 forming the jointed board unit 3000 is not limited in the camera module 100 of the present disclosure.

For example, in this specific example of the camera module 100 of the present disclosure, after the substrate 31 is provided or manufactured, all of the electronic components 32 may be conductively connected to the substrate 31 on the back face 312 of the substrate 31 by way of attaching. It can be understood by those skilled in the art that in other examples of the camera module 100 of the present disclosure, only a part of the electronic component 32 may also be connected to the substrate 31 on the back face 312 of the substrate 31, and the examples shown in FIG. 1 to FIG. 9 of the present disclosure do not limit the content and scope of the camera module 100 of the present disclosure.

In addition, the position where the electronic component 32 is attached on the back face 312 of the substrate 31 is not limited, and may be adjusted according to the specific application requirements of the camera module 100. In some examples of the camera module 100 of the present disclosure, a plurality of the electronic components 32 may be disposed in all area of the back face 312 of the substrate 31, and in some other specific examples of the camera module 100 of the present disclosure, a plurality of the electronic components 32 may also be disposed in a specific area of the back face 312 of the substrate 31, for example, in a corner, a side, or two sides, etc.

At the stage shown in FIG. 2 , the photosensitive chip 20 is attached to the attaching area 312 of the substrate 31, and the connection wire 1000 is formed between the chip connector 21 of the photosensitive chip 20 and the substrate connectors 315 of the substrate 31 through a wiring process so as to be conductively connected to the photosensitive chip 20 and the substrate 31. For example, the photosensitive chip 20 may be attached to the attaching area 313 of the substrate 31 by a surface mounting technology (SMT), and the chip connector 21 of the photosensitive chip 20 and the substrate connector 315 of the substrate 31 may be made to correspond to each other, and then by a wiring process, the connection wire 1000 is formed between the chip connector 21 of the photosensitive chip 20 and the substrate connector 315 of the substrate 31. It is worth mentioning that the wiring direction of the connection wire 1000 may not be limited. For example, the wiring direction of the connection wire 1000 may be from the photosensitive chip 20 to the substrate 31, or also may be from the substrate 31 to the photosensitive chip 20, which is selected as needed.

In addition, it is also worth mentioning that although FIG. 2 to FIG. 10 show that the photosensitive chip 20 and the substrate 31 are connected by means of the connection wire 1000 formed between the chip connector 21 of the photosensitive chip 20 and the substrate connector 315 of substrate 31, in other examples of the camera module 100 of the present disclosure, the photosensitive chip 20 and the substrate 31 may be connected to each other by other means, for example, the chip connector 21 of the photosensitive chip 20 can be directly connected to the substrate connector 315 of the substrate 31 when the photosensitive chip 20 is attached to the attaching area 313 of the substrate 31.

At the stage shown in FIGS. 3A and 3B, the jointed board unit 3000 is placed in a molding die 300 to perform a molding process by the molding die 300.

Specifically, the molding die 300 comprises an upper die 301 and a lower die 302, wherein at least one of the upper die 301 and the lower die 302 can be operated to enable the molding die 300 to be subjected to clamping and demolding operations. For example, in one example, after placing the jointed board unit 3000 in the lower die 302 and performing the clamping operation on the molding die 300, at least a first molding space 303 a is formed between the upper die 301 and the front face 311 of and the substrate 31, and at least a second molding space 303 b is formed between the lower die 302 and the back face 312 of the substrate 31.

In one example of the present disclosure, at least one of the first molding spaces 303 a and at least one of the second molding spaces 303 b are in communication with each other to subsequently allow a fluid medium 400 to fill the first molding space 303 a and the second molding space 303 b, to simultaneously form the molding base 42 integrally bonded to the front face 311 of the substrate 31 and the back molding portion 41 integrally bonded to the back face 312 of the substrate 31.

Preferably, when the number of the first molding spaces 303 a exceeds two, at least one first communication channel 304 a may also be formed between the upper die 301 and the front face 311 of the substrate 31 for connecting the adjacent first molding spaces 303 a. Correspondingly, when the number of the second molding spaces 303 b exceeds two, at least one second communication channel 304 b may also be formed between the lower die 302 and the back face 312 of the substrate 31 for connecting the adjacent second molding spaces 303 b.

With continued reference to FIGS. 3A and 3B, the upper die 301 further comprises an upper molding guide portion 3011 and at least one light window molding portion 3012 and has at least one upper molding guide groove 3013, wherein the light window molding portion 3012 integrally extends over the upper molding guide portion 3011 to form the upper molding guide groove 3013 between the light window molding portion 3012 and the upper molding guide portion 3011 or to form the upper molding guide groove 3013 between the adjacent light window molding portions 3012.

Further, the upper molding guide portion 3011 has a first upper pressing portion 30111, so that after the molding die 300 is subjected to a clamping process, the first upper pressing portion 30111 of the upper molding guiding portion 3011 can be pressed against the front face 311 of the substrate 31.

The light window molding portion 3012 has a second upper pressing portion 30121 which may have a ring shape. For example, in the example of the molding die 300 shown in FIGS. 3A and 3B, the light window molding portion 3012 may form the second upper pressure portion 30121 around in a manner of forming a safe space 30122 by indent, so that when the molding die 300 is subjected to a clamping process, the second upper pressing portion 30121 of the light window molding portion 3012 can be pressed against the non-photosensitive area of the photosensitive chip 20, and enable the photosensitive area of the photosensitive chip 20 to correspond to the safe space 30122 of the light window molding portion 3012 so as to prevent the upper die 301 from scratching the photosensitive area of the photosensitive chip 20.

It can be understood that, when the clamping operation is performed on the molding die 300, the first molding space 303 a is formed at a position corresponding to the upper molding guide groove 3013 of the upper die 301. Moreover, the second upper pressing portion 30121 of the light window molding portion 3012 of the upper die 301 surrounds the photosensitive area in a manner of being pressed against the non-photosensitive area of the photosensitive chip 20 so as to prevent the fluid medium 400 added to the first molding space 303 a from entering the photosensitive area of the photosensitive chip 20 in the molding process, thereby avoiding contamination of the photosensitive area of the photosensitive chip 20 in the molding process.

With continued reference to FIGS. 3A and 3B, the lower die 302 further comprises a lower molding guide portion 3021 and at least one support portion 3022 and has at least a lower molding guide groove 3023, wherein the support portion 3022 integrally extends over the lower molding guide portion 3021 to form the lower molding guide groove 3023 between the support portion 3022 and the lower molding guide portion 3021, or to form the lower molding guide groove 3023 between the adjacent support portions 3022.

When the clamping operation is performed on the molding die 300, the second molding space 303 b is formed at a position corresponding to the lower molding guide groove 3023 of the lower die 302. Further, the lower molding guide portion 3021 of the lower die 302 can be pressed against the back face 312 of the substrate 31, and the support portion 3022 of the lower die 302 is pressed against the back face 312 of the substrate 31.

Preferably, the height of the support portion 3022 of the lower die 302 is greater than the height of the electronic component 32 protruding from the back face 312 of the substrate 31. In this way, when the lower die 302 is pressed against the back face 312 of the substrate 31, there is a safe distance between the surface of the electronic component 32 and the inner surface of the lower die 302 to protect the surface of the electronic component 32 from being scratched by preventing the surface of the electronic component 32 from contacting the inner surface of the lower die 302. In addition, by having a safe distance between the surface of the electronic component 32 and the inner surface of the lower die 320, it is also possible to subsequently embed the electronic component 32 by the back molding portion 41 integrally bonded to the back face 312 of the substrate 31.

In addition, the molding die 300 further comprises at least one film layer 305. For example, in this specific example of the present disclosure, the number of the film layers 305 may be implemented as two, wherein one of the film layers 305 is disposed on the inner surface of the upper die 301 in an overlapping manner, and another of the film layers 305 is disposed on the inner surface of the lower die 302 in an overlapping manner, for example, the film layer 305 can be disposed on the inner surface of the upper die 301 in an overlapping manner by means of attaching the film layer 305 to the inner surface of the upper die 301, and the film layer 305 can be disposed on the inner surface of the lower die 302 in an overlapping manner by means of attaching the film layer 305 to the inner surface of the lower die 302.

It can be understood by those skilled in the art that when the molding die 300 is subjected to a clamping operation, the film layer 305 is held between the second upper pressing portion 30121 of the light window molding portion 3012 and the non-photosensitive area of the photosensitive chip 20, so that the film layer 305 prevents, by means of deformation when it is pressed, a gap from being formed between the second upper pressing portion 30121 of the light window molding portion 3012 and the non-photosensitive area of the photosensitive chip 20. Therefore, in a subsequent molding process, the fluid medium 400 is prevented from entering a safe space 30122 between the second upper pressing portion 30121 of the light window molding portion 3012 and the non-photosensitive area of the photosensitive chip 20, thereby preventing the photosensitive area of the photosensitive chip 20 held in the safe space 30122 from being contaminated, and avoiding an undesirable phenomenon of “flash” so as to ensure the good product yield of the camera module 100.

It can be understood that the film layer 305 can isolate the second upper pressing portion 30121 of the light window molding portion 3012 from the photosensitive chip 20, so that when the molding die 300 is clamped, on one hand, the film layer 305 can absorb the impact force generated by the molding die 300 when being clamped by means of deformation to prevent the impact force from directly acting on the photosensitive chip 20, and on the other hand, the film layer 305 can also isolate the second upper pressing portion 30121 of the light window molding portion 3012 from the photosensitive chip 20 to prevent the photosensitive chip 20 from being scratched.

In addition, after the molding process is completed, the film layer 305 can isolate the inner surface of the upper die 301 from the molding base 42, and isolate the inner surface of the lower die 302 from the back molding portion 41 so as to perform a demolding operation on the molding die 300, and in the process, the molding base 42 and the back molding portion 41 are prevented from being damaged.

After the clamping operation is performed on the molding die 300, the first upper pressing portion 30111 of the upper molding guide portion 3011 of the upper die 301 can also be pressed against the front face 311 of the substrate 31, so that on one hand, the film layer 305 held between the first upper pressing portion 30111 of the upper molding guide portion 3011 and the front face 311 of the substrate 31 is capable of absorbing the impact force generated by the molding die 300 when being clamped so as to prevent the impact force from directly acting on the substrate 31, and on the other hand, the film layer 305 is also capable of isolating the first upper pressure portion 30111 of the upper molding guide portion 3011 from the front face 311 of the substrate 31 so as to prevent the front face 311 of the substrate 31 from being scratched, thereby ensuring the good electrical property of the substrate 31. In addition, the film layer 305 can also prevent a gap from being formed between the first upper pressing portion 30111 of the upper molding guide portion 3011 and the front face 311 of the substrate 31 by means of deformation.

It can be understood that a part of the non-photosensitive area of the photosensitive chip 20, the connection wire 1000, and at least a part of the bonding area 314 of the substrate 31 are held in the first molding space 303 a.

After the clamping operation is performed on the molding die 300, the lower molding guide portion 3021 and the support portion 3022 of the lower die 302 are respectively pressed against different positions of the back face 312 of the substrate 31. Therefore, on one hand, the film layer 305 held between the lower molding guide portion 3021 and the back face 312 of the substrate 31 and the film layer 305 held between the support portion 3022 and the back face 312 of the substrate 31 can absorb the impact force generated by the molding die 300 when being clamped so as to prevent the impact force from directly acting on the back face 312 of the substrate 31, and on the other hand, the film layer 305 is also capable of isolating the lower molding guide portion 3021 from the back face 312 of the substrate 31 and isolating the support portion 3022 from the back face 312 of the substrate 31 so as to prevent the back face 312 of the substrate 31 from being scratched, thereby ensuring the good electrical property of the substrate 312. In addition, the film layer 305 is also capable of preventing a gap from being formed between the lower molding guide portion 3021 and the back face 312 of the substrate 31 and preventing a gap form being formed between the support portion 3022 and the back face 312 of the substrate 31 by means of deformation.

Alternatively, after the clamping operation is performed on the molding die 300, the first upper pressing portion 30111 of the upper molding guide portion 3011 of the upper die 301 may also be directly press-fitted together with at least a part of the lower molding guide portion 3012 of the lower die portion 302, such that at least one of the first molding spaces 303 a and at least one of the second molding spaces 303 b are in communication.

Preferably, after the clamping operation is performed on the molding die 300, positions of the second upper pressing portion 30121 of the light window molding portion 3012 of the upper die 301 and the support portion 3022 of the lower die 302 correspond to each other, thereby preventing the photosensitive chip 20 and the substrate 31 from being deformed by uneven forces. For example, in this example of the present disclosure, when the second upper pressing portion 30121 of the light window molding portion 3012 of the upper die 301 is pressed against the non-photosensitive area of the photosensitive chip 20, which causes a deformation generating a downward displacement of the photosensitive chip 20 and the substrate 31, the support portion 3022 of the lower die 302 is pressed against a position of the substrate 31 corresponding to the non-photosensitive area of the photosensitive chip 20 to support the substrate 31 upward so as to prevent the photosensitive chip 20 and the substrate 31 from having a deformation generating a downward displacement. In this way, the flatness of the substrate 31 and the photosensitive chip 20 can be ensured, so that the good product yield of the camera module 100 is further ensured.

At the stage shown in FIGS. 4 and 5 , the fluid medium 400 is added to at least one of the first molding spaces 303 a, or the fluid medium 400 is added to at least one of the second molding spaces 303 b, or the fluid medium 400 is simultaneously added to at least one of the first molding space 303 a and the at least one of the second molding spaces 303 b, because the adjacent first molding spaces 303 a are connected through the first communication passage 304 a, the adjacent second molding spaces 303 b are connected through the second communication channel 304 b, so that the fluid medium 400 will fill all of the first molding spaces 303 a and all of the second molding spaces 303 b.

It is worth mentioning that the fluid medium 400 can be a liquid, a solid or a mixture of liquid and solid, etc., to enable the fluid medium 400 to flow. In addition, the fluid medium 400 can be implemented as, but not limited to, a thermosetting material. Of course, it can be understood by those skilled in the art that in other possible examples, it is also possible that the fluid medium 400 is implemented as a photo-curable material or a self-curable material.

After the fluid medium 400 fully fill the first molding space 303 a and the second molding space 303 b, the fluid medium 400 may be solidified, through heating, in the first molding space 303 a and the second molding space 303 b, and a demolding operation can be performed on the molding die 300. With reference to the stage shown in FIG. 6 , the fluid medium 400 solidified in the first molding space 303 a forms the molding base 42 which is integrally bonded to the front face 311 of the substrate 31, and the light window 420 of the molding base 42 is formed at a position corresponding to the light window molding portion 3012 of the upper die 301. The photosensitive area of the photosensitive chip 20 corresponds to the light window 420 of the molding base 42, wherein the fluid medium 400 solidified in the second molding space 303 b forms the back molding portion 41 which is integrally bonded to the back face 312 of the substrate 31, and the back molding portion 41 embeds the electronic component 32, and the corresponding position of the support portion 3022 of the lower die 302 forms the mounting space 410 of the back molding portion 41.

At the stage shown in FIG. 7 , after the demolding operation is performed on the molding die 300, the semi-finished product of the circuit board assembly 2000 can be formed. Then at the stage shown in FIG. 8A and FIG. 8B, the semi-finished product of the circuit board assembly 2000 can be divided to form the circuit board assembly 2000. It is worth mentioning that the manner of dividing the semi-finished product of the circuit board assembly 2000 is not limited in the camera module 100 of the present disclosure. For example, the semi-finished product of the circuit board assembly 2000 may be divided by means of cutting to form the circuit board assembly 2000, and the semi-finished product of the circuit board assembly 2000 may also be divided by means of etching to form the circuit board assembly 2000.

In addition, in the example shown in FIG. 8A, when the semi-finished product of the circuit board assembly 2000 is divided, the dividing direction may be from the molding base 42 to the back molding portion 41. In the example shown in FIG. 8B, in dividing the semi-finished product of the circuit board assembly 2000, the dividing direction may also be from the back molding portion 41 to the molding base 42.

At the stage shown in FIG. 9 , the filtering element 50 may be attached to the inner surface 422 of the molding base 42, and then the driver 60 assembled with the optical lens 10 is attached to the outer surface 423 of the molding base 42, to form the camera module 100 shown in FIG. 10 to FIG. 11B.

According to another aspect of the present disclosure, the present disclosure further provides a method of manufacturing the camera module 100, wherein the manufacturing method comprises the following steps:

(a) conductively connecting at least one electronic component 32 on the back face 312 of the substrate 31;

(b) simultaneously forming the back molding portion 41 integrally bonded to the substrate 31 on the back face 312 of the substrate 31 and the molding base 42 integrally bonded to the substrate 31 on a front face 311 of the substrate 31, wherein the molding base 42 has at least one light window 420;

(c) enabling the photosensitive area of the photosensitive chip 20 conductively connected to the substrate 31 to correspond to the light window 420 of the molding base 42; and

(d) holding the optical lens 10 in the photosensitive path of the photosensitive chip 20 so as to produce the camera module 100.

It is worth mentioning that in the step (a), at least one of the electronic components 32 may be conductively connected to the front face 311 of the substrate 31. That is, in some examples of the camera module 100 of the present disclosure, the electronic component 32 can be conductively connected only on the back face 312 of the substrate 31, but in some other examples of the camera module 100 of the present disclosure, the electronic component 32 is conductively connected not only on the back face 312 of the substrate 31, but also on the front face 311 of the substrate 31, that is, at least one of the electronic components 32 is conductively connected on both the front face 311 and the back face 312 of the substrate 31.

In addition, the step (c) may also precedes the step (b), so that firstly the photosensitive chip 20 is conductively connected to the substrate 31, and then the back molding portion 41 integrally bonded to the substrate 31 is formed on the back face 312 of the substrate 31 and the molding base 42 integrally bonded to the substrate 31 is formed on the front face 311 of the substrate 31 simultaneously, and the photosensitive area of the photosensitive chip 20 is made to correspond to the light window 420 of the molding base 42. Preferably, the molding base 42 may further embed the non-photosensitive area of the photosensitive chip 20. It can be understood that the photosensitive area and at least a part of the non-photosensitive area of the photosensitive chip 20 correspond to the light window 420 of the molding base 42.

FIG. 13 shows a variant implementation of the camera module 100, wherein the back molding portion 41 of the molding unit 40 can be integrally bonded to all area of the back face 312 of the substrate 31, that is, the back molding portion 41 may not be provided or formed with the mounting space 410.

FIG. 14 shows another variant implementation of the camera module 100, wherein the back molding portion 41 of the molding unit 40 is integrally bonded to at least one side portion of the back face 312 of the substrate 31, that is, the back molding portion 41 may not be bonded to the middle portion of the back face 312 of the substrate 31. For example, in this specific example of the camera module 100 shown in FIG. 14 , the back molding portion 41 can be integrally bonded to the four side portions of the back face 312 of the substrate 31, so that the back molding portion 41 is in the shape of “

”. However, in another variant implementation of the camera module 100 shown in FIG. 15 , the back molding portion 41 can be integrally bonded to three side portions of the back face 312 of the substrate 31, so that the back molding portion 41 is in the shape of “Π” or in the shape of “C”. However, in another variant implementation of the camera module 100 shown in FIG. 16 , the back molding portion 41 can be integrally bonded to two side portions of the back face 312 of the substrate 31, so that the back molding portion 41 is in the shape of “Γ” or in the shape of “L”. However, in another variant implementation of the camera module 100 shown in FIG. 17 , the number of the back molding portions 41 can be two, and each of the back molding portions 41 is integrally bonded to one side portion of the back face 312 of the substrate 31 respectively, wherein two of the back molding portions 41 are symmetrical with each other, or two of the back molding portions 41 are parallel to each other. For example, the two back molding portions 41 may have a “II” shape. However, in another variant implementation of the camera module 100 shown in FIG. 18 , the back molding portion 41 may be integrally bonded only to one side portion of the back face 312 of the substrate 31. For example, the back molding portion 41 may have an “I” shape.

It is worth mentioning that those skilled in the art would understand that the back molding portion 41 can also have other shapes, such as an “X” shape, or a “

For example, the module connection side 331A of the connection plate 33A and the substrate 31A may be connected by, but are not limited to, conductive glue.

Nonetheless, it can be understood by those skilled in the art that the module connection side 331A of the substrate 31A is connected to the side face of the substrate 31A, or it is possible that the module connection side 331A of the substrate 31A and the substrate 31A are integrally formed.

The photosensitive chip 20A is attached to the attaching area 313A of the substrate 31A.

It can be understood by those skilled in the art that, in contrast to the traditional arrangement of electronic components along the periphery of a photosensitive chip, in the camera module 100A of the present disclosure, the attaching area 313A of the substrate 31A and the electronic components 32A may correspond to each other in the height direction, that is, the attaching area 313A of the substrate 31A may cover at least a part of at least one of the electronic components 32A when viewed from a top view, in such a manner that the bonding area 314A of the substrate 31A does not need to be reserved as an attaching position for attaching the electronic component 32A, so that the area of the bonding area 314A of the substrate 31A can be further reduced, that is, the attaching area 313A of the substrate 31A can occupy a larger proportion of the front face 311A of the substrate 31A. In this manner, the length and width of the camera module 100A can be further reduced.

It is worth mentioning that the wiring direction of the connection wire 1000A is not limited in the camera module 100A of the present disclosure. For example, the wiring direction of the connection wire 1000A may be from the photosensitive chip 20A to the substrate 31A, and also may be from the substrate 31A to the photosensitive chip 20A. Nonetheless, it can be understood by those skilled in the art that the connection wire 1000A may also have other formation methods. In addition, the material type of the connection wire 1000A is not limited in the camera module 100A of the present disclosure.

With continued reference to FIG. 53 to FIG. 54B, the camera module 100A further comprises a molding unit 40A, wherein the molding unit 40A comprises a back molding portion 41A and a molding base 42A, wherein the back molding portion 41A is integrally bonded to at least a part of the back face 312A of the substrate 31A, and the molding base 42A is integrally bonded to at least a part of the front face 311A of the substrate 31A. Alternatively, the molding base 42A is integrally bonded to a part of an area of the front face 311A of the substrate 31A. Preferably, the molding base 42A is further integrally bonded to at least a part of the non-photosensitive area of the photosensitive chip 20A, so that the molding base 42A embeds the non-photosensitive area of the photosensitive chip 20A. Therefore, the molding base 42A, the substrate 31A, the photosensitive chip 20A, and the back molding portion 41A can be integrated.

Specifically, the back molding portion 41A may be integrally bonded to at least a part of an area of the back face 312A of the substrate 31A by a molding process. Correspondingly, the molding base 42A may also be integrally bonded to a part of an area of the front face 311A of the substrate 31A by a molding process.

The back molding portion 41A can reinforce the strength of the substrate 31A and ensure the flatness of the substrate 31A, so that the photosensitive chip 20A attached to the attaching area 313A of the substrate 31A is kept flat so as to improve the imaging quality of the camera module 100A.

The back molding portion 41A has good inertness, and when the camera module 100A is used, heat generated by the photosensitive chip 20A is transmitted to the back molding portion 41A, and the back molding portion 41A does not deform, in such a manner, the flatness of the substrate 31A and the flatness of the photosensitive chip 20A attached to the attaching area 313A of the substrate 31A are also not affected by the heat generated by the photosensitive chip 20A, thereby facilitating to ensure the flatness of the photosensitive chip 20A. In addition, the back molding portion 41A may be formed of a material having a good thermal diffusivity so that the back molding portion 41A has a good heat dissipation property. After the heat generated by the photosensitive chip 20A is conducted to the back molding portion 41A, the back molding portion 41A can radiate the heat generated by the photosensitive chip 20A to the external environment of the camera module 100A in time so as to ensure the reliability of the camera module 100A when it has been used for a long time.

In an example of the camera module 100A of the present disclosure, the height of the back molding portion 41A is higher than the height of the electronic component 32A, or the height of the back molding portion 41A is consistent with the height of the electronic component 32A, for example, the distance between surfaces of the free side face 4111A of the back molding portion 41A and the back face 312A of the substrate 31A is greater than or equal to the height between the surfaces of the free side face of the electronic component 32A and the back face 312A of the substrate 31A. With reference to FIG. 53 , it is assumed that the height of the back molding portion 41A is a parameter H and the height of the electronic component 32A protruding from the back face 312A of the substrate 31A is a parameter h, wherein the numerical value of the parameter H is greater than or equal to the numerical value of the parameter h, so that when the camera module 100A is mounted, it is possible to prevent other mounting components from contacting the electronic component 32A, thereby ensuring the reliability of the camera module 100A. It is worth mentioning that the free side face 4111A of the back molding portion 41A defined by the present disclosure is opposite to the bonding side face 4112A of the back molding portion 41A, wherein the bonding side face 4112A of the back molding portion 41 is integrally bonded to at least a part of an area of the back face 312A of the substrate 31A, with reference to FIG. 53 .

Preferably, the back molding portion 41A embeds the entire surface of at least one of the electronic components 32A. More preferably, the back molding portion 41A embeds the entire surface of the electronic component 32A.

It is worth mentioning that the back molding portion 41A can isolate the surface of the electronic component 32A from the external environment by embedding the electronic component 32A, thereby guaranteeing the good electrical property of the electronic component 32A by avoiding oxidation of the surface of the electronic component 32A.

In addition, the back molding portion 41A can isolate adjacent electronic components 32A by embedding the electronic components 32A so as to guaranteeing the imaging quality of the camera module 100A by avoiding mutual interference between the adjacent electronic components 32A. Moreover, since the back molding portion 41A can isolate the adjacent electronic components 32A, and there is no need to reserve a safe distance between the back molding portion 41A and the electronic component 32A, more electronic components 32A with larger size can be connected on a limited area of the back face 312A of the substrate 31A, for example, more electronic components 32A with larger size can be attached to a limited area of the back face 312A of the substrate 31A. In this way, the performance of the camera module 100A can be further improved.

In addition, it also can be understood by those skilled in the art that the electronic component 32A is embedded by the back molding portion 41A integrally bonded on the back face 312A of the substrate 31A, and in this manner, the surface of the electronic component 32A can be prevented from producing contaminants and the connection position between the electronic component 32A and the substrate 31A can be prevented from producing contaminants.

In addition, after the back molding portion 41A embeds the electronic component 32A located on the back face 312A of the substrate 31A, the electronic component 32A can also prevent the back molding portion 41A from falling off from the back face 312A of the substrate 31A so as to ensure the reliability of the camera module 100A.

That is, the light reflected by the object can pass through the light window 420A to be received by the photosensitive chip 20A after entering the interior of the camera module 100A from the optical lens 10A.

It can be understood by those skilled in the art that the back molding portion 41A and the molding base 42A form a part of the molding circuit board assembly 2000A.

In this way, not only the manufacturing process of the camera module 100A can be reduced, but also the height of the camera module 100A can be lowered. It is more important that during the process of manufacturing the camera module 100A, there is no need to worry that the connection medium such as glue contaminates the photosensitive area of the photosensitive chip 20A, thereby ensuring the good product yield of the camera module 100A.

The molding base 42A embeds the non-photosensitive area of the photosensitive chip 20A, so that no safe distance is required to be reserved between the molding base 42A and the photosensitive chip 20A either in the height direction of the camera module 100A or in the circumferential direction of the camera module 100A. In this way, the length and width of the camera module 100A can be further reduced and the height of the camera module 100A can be reduced. Therefore, the camera module 100A is particularly suitable for being applied to the electronic device that is intended to be lighter and thinner.

It can be understood that the molding base 42A of the molding unit 40A embeds the connection wire 1000A, thereby being capable of isolating the surface of the connection wire 1000A from the external environment to avoid oxidation of the surface of the connection wire 1000 so as to ensure the good electrical property of the connection wire 1000.

In some other examples of the camera module 100A of the present disclosure, there is a height difference between the plane where the inner surface 422A of the molding base 42A is located and the plane where the outer surface 423A is located. For example, in this specific example of the camera module 100A shown in FIG. 49 , the plane where the inner surface 422A of the molding base 42A is located is lower than the plane where the outer surface 423A is located, so that the molding base 42A forms at least one attaching groove 424A, and the attaching groove 424A of the molding base 42A is in communication with the light window 420A, wherein the filtering element 50A attached to the inner surface 422A of the molding base 42A is accommodated in the attaching groove 424A to further reduce the height of the camera module 100A.

With reference to FIG. 40 to FIG. 52 of the accompanying drawings of the present disclosure, the manufacturing process of the camera module 100A will be illustrated in the following description.

At the stage shown in FIG. 40 , the electronic component 32A is conductively connected to the substrate 31A on the back face 312A of the substrate 31A, wherein two or more of the substrates 31A are disposed to form a jointed board unit 3000A. It is worth mentioning that the arrangement of the plurality of the substrates 31A forming the jointed board unit 3000A is not limited in the camera module 100A of the present disclosure.

For example, in this specific example of the camera module 100A of the present disclosure, after the substrate 31A is provided or manufactured, all of the electronic components 32A may be conductively connected to the substrate 31A on the back face 312A of the substrate 31A by way of attaching. It can be understood by those skilled in the art that in other examples of the camera module 100A of the present disclosure, only a part of the electronic component 32A may also be connected to the substrate 31A on the back face 312A of the substrate 31A, and the examples shown in FIG. 40 to FIG. 53 of the present disclosure do not limit the content and scope of the camera module 100A of the present disclosure.

In addition, the position where the electronic component 32A is attached on the back face 312A of the substrate may also not be limited, and may be adjusted according to the specific application requirements of the camera module 100A. In some examples of the camera module 100A of the present disclosure, a plurality of the electronic components 32A may be disposed in all area of the back face 312A of the substrate 31A, and in other specific examples of the camera module 100A of the present disclosure, a plurality of the electronic components 32A may also be disposed in a specific area of the back face 312A of the substrate 31A, for example, in a corner, a side, or two sides, etc.

At the stage shown in FIG. 41 , the jointed board unit 3000A is placed in a back molding die 500A to form the back molding portion 41A integrally bonded to at least a part of the area of the back face 312A of the substrate 31A by performing a molding process by the back molding die 500A.

Specifically, the back molding die 500A comprises a back upper die 501A and a back lower die 502A, wherein at least one of the back upper die 501A and the back lower die 502A can be operated to enable the back molding die 500A to be subjected to clamping and demolding operations.

When the jointed board unit 3000A is placed on the back molding die 500A, and a clamping operation is performed on the back molding die 500A so that the back upper die 501A and the back lower die 502A are respectively pressed against the substrate 31A on the back face 312A and the front face 311A of the substrate 31A, at least one back molding space 503A is formed between the back upper die 501A and the back face 312A of the substrate 31A. It can be understood that the electronic component 32A that is conductively connected to the substrate 31A on the back face 312A of the substrate 31A is accommodated in the back face molding space 503A so as to prevent a back upper die pressing portion 5011A of the back upper die 501A from being pressed against the electronic component 32A.

Preferably, the depth of the back molding space 503A of the back upper die 501A is greater than the height that the electronic component 32A protrudes from the back face 312A of the substrate 31A. In this manner, when the back face upper die 501A is pressed against the back face 312A of the substrate 31A, a safe distance is provided between the surface of the electronic component 32A and the inner surface of the back upper die 501A so as to prevent the surface of the electronic component 32A from being scratched by means of preventing the surface of the electronic component 32A from being in contact with the inner surface of the back upper die 501A. In addition, by providing a safe distance between the surface of the electronic component 32A and the inner surface of the back upper die 501A, it is also possible for the back molding portion 41A that is integrally bonded to at least a part of an area of the back face 312A of the substrate 31A to embed the electronic component 32A subsequently.

Further, the back lower die 502A is recessed to form a back safe space 5021A, wherein the substrate connector 315A protruding from the front face 311A of the substrate 31A can be accommodated in the back safe space 5021A, so that when the back molding die 500A is clamped, the back lower die 502A can be prevented from being pressed against the substrate connector 315A of the substrate 31A. In this way, the electrical property and reliability of the substrate 31A can be ensured.

In addition, the back molding die 500A further comprises at least one back film layer 505A. For example, in this specific example of the present disclosure, the number of the back film layers 505A may be implemented as two, one of the back film layers 505A is disposed on the inner surface of the back upper die 501A in an overlapping manner, and the other back film layer 505A is disposed on the inner surface of the back lower die 502A in an overlapping manner. For example, the back film layer 505A is disposed on the inner surface of the back upper die 501A in an overlapping manner by attaching the back film layer 505A to the back upper die 501A, and the back film layer 505A is disposed on the inner surface of the back lower die 502A in an overlapping manner by attaching the back film layer 505A to the back lower die 502A.

It can be understood that when the back molding die 500A is subjected to a clamping operation, the back film layer 505A that is disposed on the inner surface of the back upper die 501A in an overlapping manner is held between the back face 312A of the substrate 31A and the inner surface of the back upper die 501A, and the back film layer 505A that is overlapped disposed on the inner surface of the back lower die 502A is held between the front face 311A of the substrate 31A and the back lower die 502A. In this manner, on one hand, the back film layer 505A can prevent the back upper die 501A from directly contacting the back face 312A of the substrate 31A and prevent the back lower die 502A from directly contacting the front face 311A of the substrate 31A, thereby ensuring the good electrical property of the substrate 31A by avoiding scratching the surface of the substrate 31A; and on the other hand, the back film layer 505A can absorb, by means of deformation, the impact force generated by the back molding die 500A when being clamped so as to prevent the impact force from directly acting on the substrate 31A, thereby securing the good electrical property of the substrate 31A.

In addition, after the molding process is completed, the back film layer 505A is also capable of isolating the inner surface of the back upper die 501A from the back molding portion 41A, thereby facilitating performing a demolding operation on the back molding die 500A, and in the process, the back molding portion 41A is prevented from being damaged.

At the stage shown in FIG. 42 and FIG. 43 , the fluid medium 400A is added to the back molding space 503A, after the fluid medium 400A fills up the back molding space 503A, the fluid medium 400A may be solidified in the back molding space 503A by means of heating, after a demolding operation is performed on the back molding die 500A, the back molding portion 41A that is integrally bonded to at least a part of an area of the back face 312A of the substrate 31A is formed, and a semi-finished product of the circuit board assembly 2000A is obtained with reference to the stage shown in FIG. 44 .

It is worth mentioning that the fluid medium 400A may be liquid, solid or mixture of liquid and solid and the like so as to enable the fluid medium 400A to flow. In addition, the fluid medium 400A can be implemented as, but not limited to, a thermo-curable material. Of course, those skilled in the art would understand that in other possible examples, it is also possible that the fluid medium 400A is implemented as a photo-curable material or a self-curable material.

At the stage shown in FIG. 45 , the photosensitive chip 20A is attached to the attaching area 311A of the substrate 31A, and the connection wire 1000A is formed between the chip connector 21A of the photosensitive chip 20A and the substrate connector 315A of the substrate 31A by a wiring process so as to be conductively connected to the photosensitive chip 20A and the substrate 31A. For example, the photosensitive chip 20A may be attached to the attaching area 313A of the substrate 31A through a COB process (Chip On Board), and the chip connector 21A of the photosensitive chip 20A and the substrate connector 315A of the substrate 31A may be made to correspond to each other, and then the connection wire 1000A is formed between the chip connector 21A of the photosensitive chip 20A and the substrate connector 315A of the substrate 31A by a wiring process. It is worth mentioning that the wiring direction of the connection wire 1000A may not be limited. For example, the wiring direction of the connection wire 1000A may be from the photosensitive chip 20A to the substrate 31A, and also may be from the substrate 31A to the photosensitive chip 20A, which is selected as needed.

In addition, it is also worth mentioning that although FIG. 45 shows that the photosensitive chip 20A and the substrate 31A are connected by means of the connection wire 1000A formed between the chip connector 21A of the photosensitive chip 20A and the substrate connector 315A of the substrate 31A, in other examples of the camera module 100A of the present disclosure, the photosensitive chip 20A and the substrate 31A may be connected to each other by other means, for example, the chip connector 21A of the photosensitive chip 20A is directly connected to the substrate connector 315A of the substrate 31A when the photosensitive chip 20A is attached to the attaching area 313A of the substrate 31A.

At the stage shown in FIG. 46A and FIG. 46B, a semi-finished product of the circuit board assembly 2000A is placed in a front molding die 600A so as to perform a molding process via the front molding die 600A, thereby forming the molding base 42A that is integrally bonded to a part of an area of the front face 311A of the substrate 31A.

Specifically, the front molding die 600A comprises a front upper die 601A and a front lower die 602A, wherein at least one of the front upper die 601A and the front lower die 602A can be operated to enable the front molding die 600A to be subjected to clamping and demolding operations.

When the semi-finished product of the circuit board assembly 2000A is placed in the front molding die 600A and a clamping operation is performed on the front molding die 600A so that the front upper die 601A and the front lower die 602A are respectively pressed against the front face 311A of the substrate 31A and the back molding portion 41A, at least one front molding space 603A is formed between the front upper die 601A and the front face 311A of the substrate 31A. Preferably, when the number of the front molding spaces 603A formed between the front upper die 601A and the front face 311A of the substrate 31A is two or more, at least one front communication channel 604A may also be formed between the front upper die 601A and the front face 311A of the substrate 31A, wherein at least one of the front communication channel 604A can enable adjacent front molding spaces 603A to be in communication so as to subsequently allow the fluid medium 400A to flow from one of the front molding spaces 603A to another front molding space 603A via the front communication channel 604A.

With reference to FIG. 46A and FIG. 46B, the front upper die 601A further comprises a molding guide portion 6011A and at least one light window molding 6012A and has at least one molding guide groove 6013A, wherein the light window molding portion 6012A integrally extends over the molding guide portion 6011A so as to form the molding guide groove 6013A between the light window molding portion 6012A and the molding guide portion 6011A or to form the molding guide groove 6013A between adjacent window molding portions 6012A.

Further, the molding guide portion 6011A has at least one first pressing portion 60111A, so that after the front molding die 600A is subjected to a clamping process, the first pressing portion 60111A of the molding guiding portion 6011A can be pressed against the front face 311A of the substrate 31A.

The light window molding portion 6012A has a second pressing portion 60121A which may have a ring shape. For example, in the example of the front molding die 600A shown in FIG. 46A and FIG. 46B, the light window molding portion 6012A may form the second pressing portion 60121A around in a manner of recessing to form a front safe space 60122A, so that after the front molding die 600A is subjected to a clamping process, the second pressing portion 60121A of the light window molding portion 6012A can be pressed against the non-photosensitive area of the photosensitive chip 20A, and can make the photosensitive area of the photosensitive chip 20A to correspond to the front safe space 60122A of the light window molding portion 6012A so as to prevent the front upper die 601A from scratching the photosensitive area of the photosensitive chip 20A.

It can be understood that, when the clamping operation is performed on the front molding die 600A, the front molding space 603A is formed at a position corresponding to the molding guide groove 6013A of the front upper die 601A. Moreover, the second pressing portion 60121A of the light window molding portion 6012A of the front upper die 601A surrounds the photosensitive area of the photosensitive chip 20A in a manner of being pressed against the non-photosensitive area of the photosensitive chip 20A so as to prevent the fluid medium 400A that is added to the front molding space 603A from entering the photosensitive area of the photosensitive chip 20A in a subsequent molding process, thereby avoiding contamination of the photosensitive area the photosensitive chip 20A in the molding process.

In addition, the front molding die 600A further comprises at least one front film layer 605A, wherein the front film layer 605A is disposed on an inner surface of the front upper die 601A in an overlapping manner, for example, the front film layer 605A may be disposed on the inner surface of the front upper die 601A in an overlapping manner by being attached to the inner surface of the front upper die 601A. Preferably, the front film layer 605A may also be disposed on an inner surface of the front lower die 602A in an overlapping manner.

It can be understood by those skilled in the art that when the front molding die 600A is subjected to a clamping operation, the front film layer 605A is held between the second pressing portion 60121A of the light window molding portion 6012A and the non-photosensitive area of the photosensitive chip 20A, so that the front film layer 605A prevents, by means of deformation when being pressed, a gap from being formed between the second pressing portion 60121A of the light window molding portion 6012A and the non-photosensitive area of the photosensitive chip 20A. Therefore, in a subsequent molding process, the fluid medium 400A is prevented from entering the front safe space 60122A between the second pressing portion 60121A of the light window molding portion 6012A and the photosensitive area of the photosensitive chip 20A, thereby avoiding contamination of the photosensitive area of the photosensitive chip 20A held in the front safe space 60122A, and avoiding an undesirable phenomenon of “flash” so as to ensure the good product yield of the camera module 100A.

It can be understood that the front film layer 605A can isolate the second pressing portion 60121A of the light window molding portion 6012A from the photosensitive chip 20A, so that when the front molding die 600A is clamped, on one hand, the front film layer 605A can absorb the impact force generated by the front molding die 600A when being clamped by means of deformation so as to prevent the impact force from directly acting on the photosensitive chip 20A, and on the other hand, the front film layer 605A is also capable of isolating the second pressing portion 60121A of the light window molding portion 6012A from the photosensitive chip 20A so as to prevent the photosensitive chip 20A from being scratched.

In addition, after the molding process is completed, the front film layer 605A can isolate the inner surface of the front upper die 601A from the molding base 42A, thereby facilitating performing a demolding operation on the front molding die 600A, and in the process, the molding base 42A is prevented from being damaged.

Correspondingly, the front film layer 605A can also be held between the first pressing portion 60111A of the molding guide portion 6011A and the front face 311A of the substrate 31A so as to protect the substrate 31A.

It can be understood that a part of the non-photosensitive area of the photosensitive chip 20A, the connection wire 1000A, and at least a part of the bonding area 314A of the substrate 31A are held in the front molding space 603A.

After the clamping operation is performed on the front molding die 600A, the first pressing portion 60111A of the molding guide portion 6011A of the front upper die 601A is pressed against a position of the substrate 31A where the back molding portion 41A is bonded. In this way, the substrate 31A can be prevented from being damaged or deformed due to the first pressing portion 60111A of the molding guide portion 6011A being pressed, thereby ensuring the reliability of the circuit board assembly 2000A.

At the stage shown in FIG. 47 and FIG. 48 , the fluid medium 400A is added to at least one of the front molding spaces 603A, wherein the fluid medium 400A added to the front molding space 603A can be filled into adjacent front molding spaces 603A via the front communication channel 604A. After the fluid medium 400A fills up all the front molding spaces 603A, the fluid medium 400A may be solidified in the front molding space 603A by heating, and the front molding die 600A may be subjected to a demolding operation with reference to the stage shown in FIG. 49 , wherein the fluid medium 400A solidified in the front molding space 603A forms the molding base 42A that is integrally bonded to the front face 311A of the substrate 31A and the non-photosensitive area of the photosensitive chip 20A, and the light window 420A of the molding base 42A is formed at a position corresponding to the light window molding portion 6012A of the front upper die 601A, and wherein the photosensitive area of the photosensitive chip 20A corresponds to the light window 420A of the molding base 42A.

It is worth mentioning that although the drawings of the present disclosure show that the back molding portion 41A that is integrally bonded to at least a portion of an area of the back face 312A of the substrate 31A is formed first, and then, the molding base 42A that is integrally bonded to at least a part of an area of the front face 311A of the substrate 31A is formed, it can be understood by those skilled in the art that in the camera module 100A of the present disclosure, it is also possible to first form the molding base 42A that is integrally bonded to at least a part of an area of the front face 311A of the substrate 31A, and then, to form the back molding portion 41A that is integrally bonded to the back face 312A of the substrate 31A. At this point, the length of the molding base 42A may be greater than the length of the back molding portion 41A.

At the stage shown in FIG. 50 , after the demolding operation is performed on the front molding die 600A, the semi-finished product of the circuit board assembly 2000A can be formed. Then, at the stage shown in FIG. 51A and FIG. 51B, the semi-finished product of the circuit board assembly 2000A can then be divided so as to form the circuit board assembly 2000A. It is worth mentioning that the manner of dividing the semi-finished product of the circuit board assembly 2000A is not limited in the camera module 100A of the present disclosure. For example, the semi-finished product of the circuit board assembly 2000A may be divided by means of cutting so as to form the circuit board assembly 2000A, and the semi-finished product of the circuit board assembly 2000A may also be divided by means of etching so as to form the circuit board assembly 2000A.

In addition, in the example shown in FIG. 51A, when dividing the semi-finished product of the circuit board assembly 2000A, the dividing direction may be from the molding base 42A to the back molding portion 41A. In the example shown in FIG. 51B, when dividing the semi-finished product of the circuit board assembly 2000A, the dividing direction may also be from the back molding portion 41A to the molding base 42A.

At the stage shown in FIG. 52 , the filtering element 50A may be sequentially attached to the inner surface 422A of the molding base 42A, and the driver 60A assembled with the optical lens 10A is attached to the outer surface 423A of the molding base 42A so as to form the camera module 100A shown in FIG. 53 to FIG. 54B.

According to another aspect of the present disclosure, the present disclosure further provides a method for manufacturing the camera module 100A, wherein the manufacturing method comprises the following steps:

(a) connecting at least one electronic component 32A to the substrate 31A on the back face 312A of the substrate 31A conductively;

(b) bonding the back molding portion 41A to at least a part of an area of the back face 312A of the substrate 31A integrally by a molding process;

(c) bonding the molding base 42A to a part of an area of a front face 311A of the substrate 31A integrally by a molding process, and forming a light window 420A of the molding base 42A while the molding base 42A is formed;

(d) enabling a photosensitive area of a photosensitive chip 20A conductively connected to the substrate 31A to correspond to the light window 420A of the molding base 42A; and

(e) holding an optical lens 10A in a photosensitive path of the photosensitive chip 20A, and forming a light path between the optical lens 10A and the photosensitive chip 20A by the light window 420A of the molding base 42A, thereby producing the camera module 100A.

It is worth mentioning that in the step (a), at least one of the electronic components 32A may also be conductively connected to the front face 311A of the substrate 31A. That is, in some examples of the camera module 100A of the present disclosure, the electronic component 32A may only be conductively connected to the back face 312A of the substrate 31A, but in other examples of the camera module 100A of the present disclosure, the electronic component 32A is conductively connected not only to the back face 312A of the substrate 31A, but also to the front face 311A of the substrate 31A, that is, at least one of the electronic components 32A is conductively connected to both the front face 311A and the back face 312A of the substrate 31A.

In addition, the step (d) may also precede the step (c) or the step (b), so that the photosensitive chip 20A is conductively connected to the substrate 31A first, and then, the back molding portion 41A that is integrally bonded to the substrate 31A on the back face 312A of the substrate 31A and the molding base 42A that is integrally bonded to the substrate 31A on the front face 311A of the substrate 31A are formed simultaneously, and the photosensitive area of the photosensitive chip 20A is enabled to correspond to the light window 420A of the molding base 42A. Preferably, the molding base 42A may further embed the non-photosensitive area of the photosensitive chip 20A. It can be understood that the photosensitive area and at least a part of the non-photosensitive area of the photosensitive chip 20A correspond to the light window 420A of the molding base 42A.

It is worth mentioning that in another example, the step (c) precedes the step (b), so that the molding base 42A is integrally bonded to the front face 311A of the substrate 31A first, and then, the back molding portion 41A is integrally bonded to the back face 311 of the substrate 31A.

In addition, in the step (d), the photosensitive chip 20A is attached to the front face 311A of the substrate 31A through the light window 420A of the molding base 42A, so that the photosensitive chip 20A is conductively connected to the substrate 31A, and the photosensitive area of the photosensitive chip 20A is made to correspond to the light window 420A of the molding base 42A. Alternatively, the step (d) precedes the step (c), so that the photosensitive chip 20A is attached to the front face 311A of the substrate 31A first so as to connecting the photosensitive chip 20A to the substrate 31A conductively, and then, the molding base 42A is integrally bonded to the front face 311A of the substrate 31A so as to enable the photosensitive area of the photosensitive chip 20A to correspond to the light window 420A of the molding base 42A.

In this way, the module connection side 331A of the connection plate 33A can be prevented from protruding so as to ensure the reliability of a connection position between the module connection side 331A of the connection plate 33A and the back face 312A of the substrate 31A. Nonetheless, it can be understood by those skilled in the art that in other examples of the camera module 100A of the present disclosure, the back molding portion 41A may also embed a connection position between the module connection side 331A of the connection plate 33A and the substrate 31A so as to prevent the module connection side 331A of the connection plate 33A from falling off from the back face 312A of the substrate 31A, thereby ensuring the reliability of the camera module 100A.

In some other possible examples of the camera module 100A, the electronic component 32A that is not embedded by the back molding portion 41A may also be accommodated in the mounting space 410A of the back molding portion 41A. In this way, when the camera module 100A is moved or mounted, the electronic component 32A can be prevented from being contacted, thereby preventing the surface of the electronic component 32A or the conductive position between the electronic component 32A and the substrate 31A from being destroyed so as to further ensure the reliability of the camera module 100A. Alternatively, a part of the surface of the electronic component 32A may be exposed in the mounting space 410A of the back molding portion 41A.

In addition, when the camera module 100A is mounted to the electronic device, the protruding mounting components of the device body 200A can also be accommodated in the mounting space 410A of the back molding portion 41A. In this way, the internal space of the device body 200A can be effectively utilized so as to facilitate lightering and thinning and miniaturization of the electronic device.

It is worth mentioning that the number, size and position of the mounting space 410A can be selected as needed so as to improve the flexibility of the camera module 100A when it is mounted.

For example, the two back molding portions 41A may be in the shape of “II”. In another variant implementation of the camera module 100A shown in FIG. 61 , the back molding portion 41A may be integrally bonded only to one side portion of the back face 312A of the substrate 31A. For example, the back molding portion 41A may be in the shape of “I”.

Nonetheless, it is also possible that each of the back molding portions 41A is integrally bonded to a middle portion of four sides of the back face 312A of the substrate 31A respectively. In addition, it can be understood by those skilled in the art that the number of the back molding portions 41A may also be implemented to be more or less, and the camera module 100A of the present disclosure is not limited in this respect.

It is worth mentioning that those skilled in the art would understand that the back molding portion 41A of the molding unit 40A may also have any other possible shapes, which will not be exemplified further in the following description of the present disclosure.

Therefore, in the molding process, when a clamping operation is performed on the front molding die 600A, the second pressing portion 60121A of the light window molding portion 6012A of the front upper die 601A of the front molding die 600A is directly pressed against the supporting element 70A, such that on one hand, the supporting element 70A can absorb the impact force generated by the front molding die 600A when being subject to the clamping operation so as to prevent the impact force from acting on the photosensitive chip 20A, and on the other hand, the supporting member 70A can prevent, by means of deformation, a gap from forming between the second pressing portion 60121A of the light window molding portion 6012A and the non-photosensitive area of the photosensitive chip 20A so as to prevent the fluid medium 400A from contaminating the photosensitive area of the photosensitive chip 20A and to avoid an undesirable phenomenon of “flash”, thereby ensuing good product yield of the camera module 100A.

For example, at least a part of the non-photosensitive area of the photosensitive chip 20A may be firstly applied with, but not limited to, a substance such as resin or glue, and then, the filtering element 50A is disposed on the photosensitive chip 20A in an overlapping manner, and the substance such as resin or glue that is applied in at least a part of the non-photosensitive area of the photosensitive chip 20A may form the buffering portion 1A that is held between the filtering element 50A and the photosensitive chip 20A.

The light reflected by the object enters the interior of the camera module 100B from the optical lens 10B, and then is received by the photosensitive chip 20B and imaged after photoelectric conversion. Electrical signals related to the image of an object obtained by the photoelectric conversion of the photosensitive chip 20B can be transmitted by the circuit board 30B, for example, the circuit board 30B can transmit the electrical signals related to the image of the object to the device body 200B that is connected to the circuit board 30B. That is, the circuit board 30B can be conductively connected to the device body 200B to mount the camera module 100B to the device body 200B to form the electronic device.

Further, with reference to FIG. 91 , the circuit board 30B comprises a substrate 31B and at least one electronic component 32B, wherein each of the electronic components 32B is conductively connected to the substrate 31B, respectively.

Generally, the substrate 31B is plate-like, and the front face 311B and the back face 312B of the substrate 31B are parallel to each other, so that the distance between the front face 311B and the back face 312B of the substrate 31B can be used to define the thickness of the substrate 31B.

Nonetheless, it can be understood by those skilled in the art that in other examples of the camera module 100B of the present disclosure, at least one of the front face 311B and the back face 312B of the substrate 31B may be provided with a convex structure or a groove, and the camera module 100B of the present disclosure is not limited in this respect.

Further, at least one of the electronic components 32B is conductively connected to the substrate 31B on the back face 312B of the substrate 31B. Preferably, in this specific example of the camera module 100B of the present disclosure, all of the electronic components 32B may be conductively connected to the substrate 31B on the back face 312B of the substrate 31B. In this manner, the front face 311B of the substrate 31B does not need to reserve a position for connecting the electronic component 32B, thereby facilitating reducing the length and width of the camera module 100B.

It is worth mentioning that the type of the electronic component 32B is not limited in the camera module 100B of the present disclosure. For example, the electronic component 32B can be implemented as, but not limited to, a processor, a relay, a memory, a driver, a resistor, a capacitor, etc.

In this manner, the height of the camera module 100B can be further reduced. Alternatively, the electronic component 32B may also be entirely embedded inside the substrate 31B.

In addition, the circuit board 30B may further comprise a connection plate 33B, wherein the connection plate 33B has a mold connection side 331B and a device connection side 332B, and the module connection side 331B of the connection plate 33B is connected to the substrate 31B. For example, the module connection side 331B of the connection plate 33B may be connected to the front face 311B of the substrate 31B, or the module connection side 331B of the connection plate 33B may be connected to the back face 312B of the substrate 31B. Also, the manner in which the module connection side 331B of the connection plate 33B is connected to the substrate 31B is not limited. For example, the module connection side 331B of the connection plate 33B and the substrate 31B may be connected by, but are not limited to, conductive glue.

Nonetheless, it can be understood by those skilled in the art that the module connection side 331B of the substrate 31B is connected to the side face of the substrate 31B, or it is possible that the module connection side 331B of the substrate 31B and the substrate 31B are integrally formed. The device connection side 332B of the connection plate 33B can be connected to the device body 200B, for example, the device connection side 332B of the connection plate 33B can be provided or formed with a connector for being connected to the device body 200B.

Generally, the connection plate 33B can be deformed, so that the connection plate 33B can buffer, in a manner of deformation, the mounting displacement and deformation caused by the manufacturing tolerance of the camera module 100B and ensure the displacement of the camera module 100B caused by the vibration of the electronic device during usage, thereby ensuring the reliability of the electronic device when it is used.

The photosensitive chip 20B is attached to the front face 311B of the substrate 31B, and the photosensitive chip 20B is conductively connected to the substrate 31B.

Specifically, the substrate 31B has at least one attaching area 313B and at least one bonding area 314B, wherein the attaching area 313B and the bonding area 314B are both formed on the front face 311B of the substrate 31B. Generally, the attaching area 313B of the substrate 31B is located in the center, and the bonding area 314B surrounds the attaching area 313B. For example, in a specific example of the camera module 100B shown in FIG. 91 , the attaching area 313B of the substrate 31B is located at a center of the front face 311B of the substrate 31B, and the bonding area 314B of the substrate 31B is located at outer portion of the front face 311B of the substrate 31B, and the bonding area 314B surrounds the attaching area 313B. The photosensitive chip 20B is attached to the attaching area 313B of the substrate 31B.

In this manner, the length and width of the camera module 100B can be further reduced.

In addition, the manner in which the photosensitive chip 20B and the substrate 31B are connected is not limited in the camera module 100B of the present disclosure. For example, the photosensitive chip 20B has at least one chip connector 21B, and the substrate 31B has at least one substrate connector 315B. In one example of the camera module 100B of the present disclosure, the chip connector 21B of the photosensitive chip 20B may be directly connected to the substrate connector 315B of the substrate 31B, for example, when the photosensitive chip 20B is attached to the attaching area 313B of the substrate 31B, the chip connector 21B of the photosensitive chip 20B and the substrate connector 315B of the substrate 31B are directly connected.

When the camera module 100B is used, heat generated by the photosensitive chip 20B is transmitted to the back molding portion 41B, and the back molding portion 41B does not deform, in such a manner that the flatness of the substrate 31B and the flatness of the photosensitive chip 20B attached to the attaching area 313B of the substrate 31B are also not affected by the heat generated by the photosensitive chip 20B, thereby facilitating to ensure the flatness of the photosensitive chip 20B. In addition, the back molding portion 41B may be formed of a material having a good thermal diffusivity so that the back molding portion 41B has a good heat dissipation property. After the heat generated by the photosensitive chip 20B is conducted to the back molding portion 41B, the back molding portion 41B can radiate the heat generated by the photosensitive chip 20B to the external environment of the camera module 100B in time so as to ensure the reliability of the camera module 100B when it has been used for a long time.

Preferably, the back molding portion 41B may be integrally bonded to the substrate 31B on the back face 312B of the substrate 31B by a molding process.

In an example of the camera module 100B of the present disclosure, the height of the back molding portion 41B is higher than the height of the electronic component 32B, or the height of the back molding portion 41B is consistent with the height of the electronic component 32B, for example, the distance between surfaces of the free side face 4111B of the back molding portion 41B and the back face 312 of the substrate 31B is greater than or equal to the height between the surfaces of the free side face of the electronic component 32B and the back face 312B of the substrate 31B.

In addition, the back molding portion 41B can isolate adjacent electronic components 32B by embedding the electronic components 32B so as to guarantee the imaging quality of the camera module 100B by avoiding mutual interference between the adjacent electronic components 32B. Moreover, since the back molding portion 41B can isolate the adjacent electronic components 32B, and there is no need to reserve a safe distance between the back molding portion 41B and the electronic component 32B, more electronic components 32B with larger size can be connected on a limited area of the back face 312B of the substrate 31B, for example, more electronic components 32B with larger size can be attached to a limited area of the back face 312B of the substrate 31B. In this manner, the performance of the camera module 100B can be further improved.

In this way, it is possible to prevent the module connection side 331B of the connection plate 33B from protruding to ensure the reliability of the connection position between the module connection side 331B of the connection plate 33B and the back face 312B of the substrate 31B. Nonetheless, it can be understood by those skilled in the art that in other examples of the camera module 100B of the present disclosure, the back molding portion 41B can also embed the connection position between the module connection side 331B of the connection plate 33B and the substrate 31B to prevent the module connection side 331B of the connection plate 33B from falling off from the back face 312B of the substrate 31B so as to ensure the reliability of the camera module 100B.

In some other possible examples of the camera module 100B of the present disclosure, the electronic component 32B that is not embedded by the back molding portion 41B can also be accommodated in the mounting space 410B of the back molding portion 41B.

It is worth mentioning that the arrangement of the plurality of the substrates 31B forming the jointed board unit 3000B is not limited in the camera module 100B of the present disclosure, which may be selected as needed.

For example, in this specific example of the camera module 100B of the present disclosure, after the substrate 31B is provided or manufactured, all of the electronic components 32B may be conductively connected to the substrate 31B on the back face 312B of the substrate 31B in a manner of attaching.

At the stage shown in FIG. 83A and FIG. 83B, the jointed board unit 3000B is placed in a molding die 300B to perform a molding process by the molding die 300B.

Specifically, the molding die 300B comprises an upper die 301B and a lower die 302B, wherein at least one of the upper die 301B and the lower die 302B can be operated to enable the molding die 300B to be subjected to clamping and demolding operations. For example, in one example, the jointed board unit 3000B can be placed in the lower die 302B and after performing a clamping operation on the molding die 300B, at least one molding space 303B is formed between the lower die 302B and the back face 312B of the substrate 31B.

Preferably, when the number of the molding spaces 303B exceeds two, at least one communication channel 304B may also be formed between the lower die 302B and the back face 312B of the substrate 31B, wherein the communication channel 304B is used for communicating the adjacent molding space 303B. In this way, a fluid medium 400B added to one of the molding spaces 303B can fill all of the molding spaces 303B through the communication channel 304B.

It is worth mentioning that the pressing face of the upper die 301B can be a plane, which can be directly pressed against the front face 311B of the substrate 31B. Preferably, the upper die 301B can form at least one safe space 30122B by means of a concave and form an upper pressing portion 30121B around the molding space 303B, wherein when the molding die 300B is performed a clamping operation, the upper pressing portion 30121B of the upper die 301B can be pressed against an area of the substrate 31B where no wiring is left, or the upper pressing portion 30121B of the upper die 310 is pressed against an area of the jointed board unit 3000B used for supporting the substrate 31B, so that the wiring area of the substrate 31B corresponds to the safe space 30122B. In this way, the upper die 301B can be prevented from scratching or crushing the substrate 31B so as to ensure the good electrical property of the substrate 31B. It can be understood by those skilled in the art that the upper die 301B particularly facilitates protecting the substrate connector 315B protruding from the front face 311B of the substrate 31B by means of providing the safe space 30122B. That is, the substrate connector 315B protruding from the front face 311B of the substrate 31B can be accommodated in the safe space 30122B of the upper die 301B so as to prevent the substrate connector 315B of the substrate 31B from being pressed when the molding die 300B is clamped.

With continued reference to FIG. 83A and FIG. 83B, the lower die 302B further comprises a molding guide portion 3021B and at least one support portion 3022B and has at least one molding guide groove 3023B, wherein the support portion 3022B integrally extends over the molding guide portion 3021B to form the molding guide groove 3023B between the support portion 3022B and the molding guide portion 3021B, or form the molding guide groove 3023B between the adjacent support portions 3022B.

When performing the clamping operation on the molding die 300B, the molding space 303B is formed at a position corresponding to the molding guide groove 3023B of the lower die 302B. Moreover, the molding guide portion 3021B of the lower die 302B can be pressed against the back face 312B of the substrate 31B, and the support portion 3022B of the lower die 302B is pressed against the back face 312B of the substrate 31B.

Preferably, the height of the support portion 3022B of the lower die 302B is greater than the height of the electronic component 32B protruding from the back face 312B of the substrate 31B. In this way, when the lower die 302B is pressed against the back face 312B of the substrate 31B, there is a safe distance between the surface of the electronic component 32B and the inner surface of the lower die 302B to protect the surface of the electronic component 32B from being scratched by preventing the surface of the electronic component 32B from contacting the inner surface of the lower die 302B. In addition, by means of having a safe distance between the surface of the electronic component 32B and the inner surface of the lower die 302B, it is also possible to subsequently embed the electronic component 32B by the back molding portion 41B integrally bonded to the back face 312B of the substrate 31B.

In addition, the molding die 300B further comprises at least one film layer 305B. For example, in this specific example of the present disclosure, the number of the film layers 305B may be implemented as two, wherein one of the film layers 305B is disposed on the inner surface of the upper die 301B in an overlapping manner, and another of the film layers 305B is disposed on the inner surface of the lower die 302B in an overlapping manner, for example, the film layer 305B can be disposed on the inner surface of the upper die 301B in an overlapping manner by means of attaching the film layer 305B to the inner surface of the upper die 301B, and the film layer 305B can be disposed on the inner surface of the lower die 302B in an overlapping manner by means of attaching the film layer 305B to the inner surface of the lower die 302B.

It can be understood by those skilled in the art that when the molding die 300B is performed a clamping operation, the film layer 305B is held between the upper pressing portion 30121B of the upper die 301B and the front face 311B of the substrate 31B. When the molding die 300B is clamped, on one hand, the film layer 305B can absorb the impact force generated by the molding die 300B when being clamped by means of deformation to prevent the impact force from directly acting on the substrate 31B, and on the other hand, the film layer 305B can further isolate the upper pressing portion 30121B of the upper die 301B from the front face 311B of the substrate 31B to prevent the upper die 301B from scratching the substrate 31B, thereby ensuring the good electrical property of the substrate 31B.

After performing the clamping operation on the molding die 300B, the molding guide portion 3021B and the support portion 3022B of the lower die 302B are respectively pressed against different positions of the back face 312B of the substrate 31B.

The molding base 925 can be integrally molded on the front face 9211 of the circuit board 921 by a molding process, and in this aspect, it is not necessary to provide substances such as glue for connecting the molding base 925 and the circuit board 921 between the molding base 925 and the circuit board 921. In this way, not only the height of the camera module 9100 can be reduced, but also the flatness of the circuit board 921 can be effectively ensured to improve the imaging quality of the camera module 9100.

The camera module 9100 further comprises at least one driver 930, wherein the optical lens 910 is drivably disposed on the driver 930, and the driver 930 is disposed on the molding base 925, so that the optical lens 910 is held in the photosensitive path of the photosensitive chip 922 via the cooperation of the driver 930 and the molding base 925. The driver 930 can drive the optical lens 910 to move along the photosensitive path of the photosensitive chip 922 to adjust the focal length of the camera module 9100, so that the camera module 9100 has the capacities of automatic zooming and automatic focusing. Preferably, the driver 930 can be implemented as, but not limited to, a voice coil motor.

Nonetheless, in a variant implementation of the camera module 9100 shown in FIG. 117 , the camera module 9100 may not have the driver 930, for example, the camera module 9100 may comprise a lens tube 940 disposed on the molding base 925, wherein the optical lens 910 is disposed on the lens tube 940 to enable the optical lens 910 to be held in the photosensitive path of the photosensitive chip 922 via the cooperation of the lens tube 940 and the molding base 925, so that the camera module 9100 forms a fixed focus camera module.

It is worth mentioning that in this embodiment of the camera module 9100 shown in FIG. 117 , the lens tube 940 can be separately manufactured and then be attached or assembled to the molding base 925. In this embodiment of the camera module 9100 shown in FIG. 118 , the lens tube 940 can also be integrally formed by the molding base 925 extending upward.

In this example of the camera module 9100 shown in FIG. 119 , the optical lens 910 can also be directly attached to the molding base 925 such that the optical lens 910 is held in the photosensitive path of the photosensitive chip 922. In this example of the camera module 9100 shown in FIG. 120A, the exterior of the optical lens 910 may also be provided with the lens tube 940, for example, the lens tube 940 may also be attached to the molding base 925, and the optical lens 910 is located inside the lens tube 940, but the optical lens 910 and the lens tube 940 may not be in contact with each other so as to protect the optical lens 910 via the lens tube 940. It can be understood that the lens tube 940 can also be integrally formed by the molding base 925 extending upward.

In this embodiment of the camera module 9100 shown in FIG. 120B, the camera module 9100 can also comprise at least one bracket 960 for attaching the filtering element 950, wherein the bracket 960 is attached to the molding base 925 such that the filtering element 950 is held between the photosensitive chip 922 and the optical lens 910, and in this way, the size of the filtering element 950 can be reduced to reduce the cost of the camera module 9100.

With further reference to FIG. 116A, the camera module 9100 can comprise a filtering element 950, wherein the filtering element 950 is held between the photosensitive chip 922 and the optical lens 910 for filtering stray light in the light entering the interior of the camera module 9100 from the optical lens 910, thereby improving the imaging quality of the camera module 9100. The type of the filtering element 950 is not limited, for example, the filtering element 950 may be implemented as, but not limited to, an infrared cut-off filter.

Further, the molding base 925 has an outer attaching face 9252 and an inner attaching face 9253, wherein the inner attaching face 9253 surrounds the light window 9251 of the molding base 925, and the outer attaching face 9252 surrounds the inner attaching face 9253, and wherein the driver 930 or the lens tube 940 can be attached on the outer attaching face 9252 of the molding base 925, and the filtering element 950 can be attached on the inner attaching face 9253 of the molding base 925. In this way, the optical lens 910 can be held in the photosensitive path of the photosensitive chip 922, and the filtering element 950 can be held between the photosensitive chip 922 and the optical lens 910.

In an example, the outer attaching face 9252 and the inner attaching face 9253 of the molding base 925 can be in a same plane. In another example, the outer attaching face 9252 and the inner attaching face 9253 of the molding base 925 may have a height difference to form an attaching groove 9254 of the molding base 925. Specifically, the plane where the inner attaching face 9253 of the molding base 925 is located is lower than the plane where the outer attaching face 9252 is located, so that the molding base 925 forms the attaching groove 9254 at a position corresponding to the inner attaching face 9253, and therefore, the filtering element 950 attached on the inner attaching face 9253 is held in the attaching groove 9254. In this way, the height of the camera module 9100 can be further reduced.

In other examples, the circuit board assembly 920 may not have the molding base 925, but comprise a lens frame 926, wherein the lens frame 926 has a light through hole 9261, and the lens frame 926 is attached on the front face 9211 of the circuit board 921 after being separately manufactured, so that the light through hole 9261 of the lens frame 926 and the photosensitive area of the photosensitive chip 922 correspond to each other, and the driver 930 can be disposed on the lens frame 926 such that the optical lens 910 is held in the photosensitive path of the photosensitive chip 922, as shown in FIG. 121 .

It is worth mentioning that, in the example of the camera module 9100 shown in FIG. 116A, all of the electronic components 923 can be attached on the back face 9212 of the circuit board 921 by mutually spaced. In this specific example of the camera module 9100 shown in FIG. 122 , at least one of the electronic components 923 is attached on the back face 9212 of the circuit board 921, and the other electronic component 923 is attached on the front face 9211 of the circuit board 921. For the convenience of description, in this following paper, the electronic component 923 attached on the front face 9211 of the circuit board 921 is defined as a first electronic component 923 a, and the electronic component 923 attached on the back face 9212 of the circuit board 921 is defined as a second electronic component 923 b.

That is, the circuit board assembly 920 can comprise at least one of the first electronic component 923 a and at least one of the second electronic components 923 b, wherein each of the first electronic components 923 a is respectively attached on the front face 9211 of the circuit board 921 by mutually spaced, and each of the second electronic components 923 b is respectively attached on the back face 9212 of the circuit board 921 by mutually spaced.

It is worth mentioning that the electronic components 923 are divided into the first electronic components 923 a and the second electronic components 923 b according to the position where the electronic components 923 are attached to, which is only for the convenience of description and easy understanding of the camera module 9100 of the present disclosure, and it does not limit the content and scope of the camera module 9100 of the present disclosure, wherein the type of the first electronic component 923 a and the second electronic component 923 b can be the same.

In addition, the electronic components 923 that achieve the same function or the same type of function can be attached on one face of the circuit board 921, and the electronic components 923 that achieve another function or another type of function can be attached on the other face of the circuit board 921, and the camera module 9100 of the present disclosure is not limited in these respects.

After each of the first electronic components 923 a is attached on the front face 9211 of the circuit board 921 by mutually spaced, each of the first electronic components 923 a can be disposed in the circumferential direction of the photosensitive chip 922. After each of the second electronic components 923 b is attached on the back face 9212 of the circuit board 921 by mutually spaced, in the height direction of the camera module 9100, the second electronic component 923 b and the photosensitive chip 922 can overlap each other, thereby facilitating reducing the length and width of the camera module 9100 and facilitating the application of the camera module 9100 to the electronic device that is intended to be lighter and thinner and intelligent.

In this example of the camera module 9100 shown in FIG. 122 , at least one of the first electronic components 923 a can be embedded by the molding base 925. Preferably, the molding base 925 can embed all of the first electronic components 923 a. In this way, in one aspect, the first electronic component 923 a can prevent the molding base 925 from falling off from the front face 9211 of the circuit board 921; in a second aspect, the molding base 925 can prevent the first electronic component 923 a from coming into contact with the external environment, thereby prevent the surface of the first electronic component 923 a from being oxidized, etc.; in a third aspect, the molding base 925 can isolate the adjacent first electronic components 923 a, thereby preventing mutual interference from occurring to the adjacent first electronic components 923 a so as to improve imaging quality of the camera module 9100; in a fourth aspect, the molding base 925 can isolate the adjacent first electronic components 923 a such that the distance between the adjacent first electronic components 923 a is closer, thereby facilitating attaching more and larger first electronic components 923 a to the circuit board 921 with a limited area to improve the performance of the camera module 9100; in a fifth aspect, there is no need to reserve a safe distance between the molding base 925 and the first electronic component 923 a, so that the length, the width, and the height of the camera module 9100 can be reduced, thereby facilitating the miniaturization of the camera module 9100; and in a sixth aspect, the molding base 925 can isolate the first electronic component 923 a from the photosensitive area of the photosensitive chip 922 to prevent the photosensitive area of the photosensitive chip 922 from being contaminated by contaminants such as impurities falling from the surface of the first electronic component 923 a or solder powder falling from a connection position between the first electronic component 923 a and the circuit board 921, thereby facilitating ensuring the imaging quality of the camera module 9100.

In these examples of the camera module 9100 shown in FIG. 116A and FIG. 122 , the second electronic component 923 b is exposed. In these examples of the camera module 9100 shown in FIG. 123 and FIG. 124 , the second electronic component 25 b can also be embedded. Specifically, the circuit board assembly 920 further comprises at least an embedding portion 927, wherein the embedding portion 927 is integrally formed on the back face 9212 of the circuit board 921 to embed at least one of the second electronic components 923 b. Preferably, the embedding portion 927 can embed all of the second electronic components 923 b. In this way, in one aspect, the second electronic component 923 b can prevent the embedding portion 927 from falling off from the back face 9212 of the circuit board 921; in a second aspect, the embedding portion 927 can prevent the second electronic component 923 b from coming into contact with the external environment, thereby prevent the surface of the second electronic component 923 b from being oxidized, etc.; in a third aspect, the embedding portion 927 can isolate the adjacent second electronic components 923 b, thereby preventing mutual interference from occurring to the adjacent second electronic components 923 b so as to improve imaging quality of the camera module 9100; in a fourth aspect, the embedding portion 927 can isolate the adjacent second electronic components 923 b such that the distance between the adjacent second electronic components 923 b is closer, thereby facilitating attaching more and larger second electronic components 923 b to the circuit board 921 with a limited area to improve the performance of the camera module 9100; and in a fifth aspect, the embedding portion 927 can also ensure the flatness of the circuit board 921, so that the circuit board 921 can employ a plate with thinner thickness, such as an FP circuit board or a soft and hard plate, thereby facilitating reducing the height of the camera module 9100.

In this example of the camera module 9100 shown in FIG. 125 , the circuit board 921 can have at least one molding space 9213, wherein the molding space 9213 extends from the back face 9212 of the circuit board 921 toward the front face 9211, that is, the opening of the molding space 9213 is located on the back face 9212 of the circuit board 921. In this specific example of the camera module 9100 shown in FIG. 125 , each of the molding spaces 9213 of the circuit board 921 is implemented as a groove or a blind hole, respectively, so that the embedding portion 927 may be partially filled and held in each of the molding spaces 9213 of the circuit board 921 during molding. In this way, the embedding portion 927 and the circuit board 921 can be tightly and reliably bonded together. It is worth mentioning that the number, the size and the shape of the molding space 9213 of the circuit board 921 are not limited in the camera module 9100 of the present disclosure.

In these examples of the camera module 9100 shown in FIGS. 126 and 127A, the molding space 9213 of the circuit board 921 may also be implemented as a channel such that the molding space 9213 can communicate the back face 9212 921 and the front face 9211 of the circuit board. In FIG. 126 and FIG. 127A, after the embedding portion 927 is formed, a part of the embedding portion 927 can extend from the back face 9212 of the circuit board 921 to the front face 9211 of the circuit board 921 via the molding space 9213, wherein in FIG. 126 , this portion of the embedding portion 927 may not protrude from the front face 9211 of the circuit board 921, and in FIG. 127 , this portion of the embedding portion 927 may protrude from the front face 9211 of the circuit board 921.

Of course, it can be understood that a part of the molding space 9213 of the circuit board 921 can also be implemented as a groove or a blind hole, and another portion of the molding space 9213 is implemented as a channel. In addition, when the molding space 9213 of the circuit board 921 is implemented as a blind hole, in one example, only the molding space 9213 can extend from the back face 9212 of the circuit board 921 toward the front face 9211; in another example, only the molding space 9213 can extend from the front face 9211 of the circuit board 921 toward the back face 9212; or in another example, at least one of the molding spaces 9213 can extend from the front face 9211 of the circuit board 921 toward the back face 9212, and at least one of the molding spaces 9213 can extend from the back face 9212 of the circuit board 921 toward the front face 9211.

It is worth mentioning that the manner of providing the molding space 9213 described above is only an example. In other examples, the circuit board 921 may be provided with the molding spaces 9213 implemented both as a blind hole and implemented as a through hole. The camera module 9100 of the present disclosure will not be exemplified one by one. Nevertheless, it can be understood by those skilled in the art that it does not limit the content and scope of the camera module 9100 of the present disclosure.

In addition, in this example of the camera module 9100 shown in FIG. 127B, the embedding portion 927 and the molding base 925 may also be integrally formed, that is, after passing through at least one of the molding spaces 9213 of the circuit board 921, a molding material forms the molding base 925 integrally bonded to the circuit board 921 on the front face 9211 of the circuit board 921, and forms the embedding portion 927 integrally bonded to the circuit board 921 on the back face 9212 of the circuit board 921.

In this embodiment, it can be understood that the embedding portion 927 and the molding base 925 can be formed by a single molding process, for example, the circuit board 921 to which the electronic component 923 is attached can be placed in a molding die 9300, and a base molding space 9301 can be formed between the front face 9211 of the circuit board 921 and the molding die, and an embedding molding space 9302 can be formed between the back face 9212 of the circuit board 921 and the molding die, wherein at least one of the molding spaces 9213 of the circuit board 921 communicates the base molding space 9301 and the embedding molding space 9302, so that when a molding material is added to the interior of the molding die 9300, the molding material can be filled in the base molding space 9301 and the embedding molding space 9302 through the molding space 9213 of the circuit board 921. Therefore, the embedding portion 927 and the molding base 925 are integrally formed after the molding material is consolidated, and as shown in FIG. 128A, FIG. 128B, FIG. 128C and FIG. 128D, this example of the camera module 9100 shown in FIG. 127B can be obtained.

Of course, the molding base 925 and the embedding portion 927 can also be formed by two molding processes. With reference to FIG. 128E to FIG. 128K, the embedding portion 927 can be molded first, and the molding base 925 is then molded, and of course, in other examples, the molding base 925 can also be molded first, and the embedding portion 927 is then molded, and the present disclosure is not limited in this respect. In FIG. 129 , the circuit board 921 further has at least one holding through hole 9214, wherein the holding through hole 9214 communicates the front face 9211 and the back face 9212 of the circuit board 921, wherein the embedding portion 927 comprises an embedding body 9271 and at least one holding element 9272 integrally formed on the embedding body 9271, the embedding body 9271 embeds the second electronic component 923 b, each of the holding elements 9272 is held in the holding through hole 9214 of the circuit board 921, and the photosensitive chip 922 is attached to each of the holding elements 9272 of the embedding portion 927 to maintains the flatness of the photosensitive chip 922 by each of the holding elements 9272 of the embedding portion 927, so that the flatness of the photosensitive chip 922 can be not limited to the flatness of the circuit board 921, thereby enabling the circuit board 921 to be made of a thinner plate.

Although there is no example that the photosensitive chip 922 comes into contact with the front face 9211 of the circuit board 921 shown on FIG. 129 , it can be understood by those skilled in the art that in some other examples, the photosensitive chip 922 can also come into contact with the front face 9211 of the circuit board 921 to further reduce the height of the camera module 9100.

In addition, in FIG. 130 and FIG. 131 , the periphery of the embedding portion 927 may also be wrapped around the periphery of the circuit board 921 such that the embedding portion 927 and the circuit board 921 can be reliably bonded together, and the embedding portion 927 can make the circuit board 921 more flat. For example, in FIG. 130 , when the periphery of the embedding portion 927 is wrapped around the periphery of the circuit board 921, the periphery of the embedding portion 927 may not protrude from the front face 9211 of the circuit board 921, nevertheless, in the example shown in FIG. 131 , when the embedding portion 927 is wrapped around the periphery of the circuit board 921, the periphery of the embedding portion 927 may also protrude from the front face 9211 of the circuit board 921.

In these examples of the camera module 9100 shown in FIG. 132 and FIG. 133A, the circuit board 921 may further be provided with at least one accommodation space 9215, wherein the accommodation space 9215 extends from the front face 9211 of the circuit board 921 toward the back face 9212, and the photosensitive chip 922 that is electrically connected to the circuit board 921 is accommodated in the accommodating space 9215. In this way, the height of the camera module 9100 can be further reduced. In this example of the camera module 9100 shown in FIG. 132 , the accommodating space 9215 of the circuit board 921 can be implemented as a groove, and in this example of the camera module 9100 shown in FIG. 133A, the accommodation space 9215 of the circuit board 921 can also be implemented as a through hole.

It is worth mentioning that although an example in which the electronic component 923 is attached only on the back face 9212 of the circuit board 921 is shown in FIG. 132 and FIG. 133A, it can be understood by those skilled in the art that in other examples of the camera module 9100, the front face 9211 of the circuit board 921 can also be attached with the electronic component 923, and the present disclosure is not limited in this respect.

It is also worth mentioning that although the electronic component 923 attached on the back face 9212 of the circuit board 921 is embedded by the embedding portion 927 in FIG. 132 and FIG. 133A, it can be understood by those skilled in the art that in other examples of the camera module 9100, the electronic component 923 attached on the back face 9212 of the circuit board 921 is not embedded, that is, at least a part of the electronic component 923 is exposed.

In this example of the camera module 9100 shown in FIG. 133B, the circuit board 921 is provided with the accommodation space 9215, and the accommodation space 9215 is implemented as a through hole, wherein at least one of the electronic components 923 is attached on the back face 9212 of the circuit board 921. Of course, at least one of the electronic components 923 may be attached on the front face 9211 of the circuit board 921, and then the embedding portion 927 can be molded on the back face 9212 of the circuit board 921, wherein the embedding portion 927 may not embed the electronic component 923, or the embedding portion 927 may also embed at least a part of at least one of the electronic component 923, or the embedding portion 927 may embed all of the electronic components 923, and the embedding portion 927 may form an accommodating groove 9271, and the accommodating groove 9271 corresponds to the accommodation space 9215 of the circuit board 921. The photosensitive chip 922 is then attached on the embedding portion 927 through the accommodation space 9215 of the circuit board 921, and the photosensitive chip 922 is located in the accommodating groove 9271, and the circuit board 921 and the photosensitive chip 922 are connected by the lead 924. In this way, the flatness of the photosensitive chip 922 can be ensured by the embedding portion 927 so as to improve the reliability of the camera module 9100.

In this example of the camera module 9100 shown in FIG. 134 , the photosensitive chip 922 can also be conductively connected to the circuit board 921 through a flip-chip process to further reduce the height of the camera module 9100. Similarly, although the example in which the electronic component 923 is attached only on the back face 9212 of the circuit board 921 is shown in FIG. 134 , it can be understood by those skilled in the art that in other examples of the camera module 9100, the front face 9211 of the circuit board 921 can also be attached with the electronic component 923. In addition, although the electronic component 923 shown in FIG. 134 is embedded by the embedding portion 927, in other examples, at least a portion of the electronic component 923 can be exposed.

With reference to FIG. 116A, the molding base 925 can be formed only on the front face 9211 of the circuit board 921, and in this example of the camera module 9100 shown in FIG. 135 , the molding base 925 can further embed at least a part of the non-photosensitive area of the photosensitive chip 922. In this way, the molding base 925, the circuit board 921, and the photosensitive chip 922 can be integrally bonded such that the flatness of the photosensitive chip 922 can be not limited to the circuit board 921, thereby facilitating improving the imaging quality of the camera module 9100. In addition, the molding base 925 can also embed the leads 924 and isolate the adjacent leads 924 after molding.

In this example of the camera module 9100 shown in FIG. 136 , the filtering element 950 can be overlapped on the photosensitive chip 922 such that when the molding base 925 is formed, the molding base 925 can embed a portion of the filtering element 950 such that the molding base 925, the circuit board 921, the photosensitive chip 922, and the filtering element 950 are integrally bonded.

With reference to FIG. 116A, the molding base 925 and the front face 9211 of the circuit board 921 are directly bonded together, and in this example of the camera module 9100 shown in FIG. 137 , the circuit board assembly 920 further comprises a frame-shaped supporting element 928, wherein the supporting element 928 can be disposed on the front face 9211 of the circuit board 921, or the supporting element 928 is formed on the front face 9211 of the circuit board 921, so that the supporting element 928 surrounds the periphery of the photosensitive chip 922. It can be understood that the supporting element 928 protrudes from the front face 9211 of the circuit board 921. For example, in an example, glue can be applied to the front face 9211 of the circuit board 921 to form the supporting element 928 after the glue has been consolidated. The supporting element 928 can be elastic to protect the circuit board 921 when the embedding portion 927 and/or the molding base 925 are molded through a molding die. The molding base 925 can embed at least a part of the supporting element 928 after molding, for example, in this example shown in FIG. 137 , the molding base 925 can embed the outer side face of the supporting element 928 after molding. In other examples, the molding base 925 can also embed at least a part of a top surface of the supporting element 928 after molding.

In this example of the camera module 9100 shown in FIG. 138 , the supporting element 928 can also be disposed on at least a part of the non-photosensitive area of the photosensitive chip 922, or the supporting element 928 may be formed on at least a part of the non-photosensitive area of the photosensitive chip 922 such that after the molding base 925 is formed, the molding base 925 can embed at least a part of the supporting elements 928 such that the molding base 925, the lead 924, the photosensitive chip 922, and the circuit board 921 are integrally bonded. For example, in this example shown in FIG. 137 , the molding base 925 can embed the outer side face of the supporting element 928 after molding, and in other examples, the molding base 925 can embed at least a part of the top surface of the supporting element 928 after molding.
